    Special Notes on Remarkable Stars    

Here are the summaries of stars researched and analyzed in the MISAO Project, stars you reported us the information on which, and stars whose interesting features were discovered in the MISAO Project.

* EK And

It is a red variable with a range of 1.1 mag and period of 185 days, however it was not variable in fact (IBVS 5396).

* TT Boo

Outburst of this UG-type cataclysmic variable was detected, and its rapid fading was recorded, by chance in the survey in 2007 April by Nobuo Ohkura and Youichirou Nakashima. It kept bright as 14 mag from Apr. 9 to 12, then became slightly faint as 14.6 mag on Apr. 14. Then it faded rapidly down to 16.6 mag on Apr. 19. It became invisible, fainter than 17.5 mag, on Apr. 23. (Image, Light Curve).
The AAVSO database revealed that it was fainter than 16.5 mag until Mar. 31, but it brightened up to 13 mag on Apr. 1. It kept brighter than 14 mag until Apr. 17, then it faded rapidly as 16 mag on Apr. 19 and 17.5 mag on Apr. 20.

* AF Cam

Outburst of this UG-type cataclysmic variable up to 13.7 mag was detected by chance in the survey on 2007 Feb. 12 by Nobuo Ohkura and Youichirou Nakashima. It had never been brighter than 16.5 mag in the MISAO Project images between 1999 and 2002.
Yutaka Maeda reported it as "not seen", fainter than 14.1 mag, just on the same day, Feb. 12, in the VSOLJ database.
Taichi Kato commented that Gary Poyner detected it as 13.4 mag on Feb. 6 and we observed during its fading phase.

* V723 Cas

The small brightening of this nova was detected in 2001 October, about 6 years after discovery (Brightening of Nova Cas 1995).

* V426 Oph

The small outburst of this nova-like star was detected [vsnet-obs 19665]. The VSNET data shows that this outburst was caught only by the MISAO Project.

* V735 Sgr

The position of this cataclysmic variable had been ambiguous. Discovery of MisV0041 brought review of past plates and papers, then correct position was revealed. The mistake in the past paper was also revealed (IBVS 5326).

* V5558 Sgr

We measured the magnitude from the SOHO/LASCO C3 images. It was constant at about 8.9 mag between 2007 Dec. 18 and Dec. 31.
The nova was not observed on the earth at that time because conjunction with the sun. The gap of observations is about 2 months between 2007 Nov. 29 and 2008 Jan. 24 based on the AAVSO and VSOLJ database.
Here is the light curve and the SOHO/LASCO image.

* V354 Vul

The position of V354 Vul = LD 143 is revised in IBVS 4450 based on the identification with a USNO-A1.0 star. But we only found a faint 16-mag star at the position on Nobuo Ohkura and Ken-ichi Kadota's unfiltered CCD images, too faint as a Mira type variable with a V-band range of 13.2 - [15.2 mag.
We discovered a variable star with a range of 12.2 - 14.4 mag at R.A. 19h50m08s.67, Decl. +22o32'17".8 (J2000.0), 25 arcsec from the cataloged position. That must be identified with V354 Vul, and we pointed out the mis-identification in IBVS 4450 [vsnet-id 258].
Brian Skiff and Graff Williams, the authors of IBVS 4450, agreed our identification is correct and the position in IBVS 4450 is in error [vsnet-id 259].

* GCN2056 var

New eclipsing variable near by GRB 030329 (GCN 2056). Eclipsing variation was confirmed from Ken-ichi Kadota's images of GRB 030329 (light curve).
See also [vsnet-newvar 1908].

* GRB 030329

Our observations measured by Seiichi Yoshida from images taken by Ken-ichi Kadota are utilized in Ken'ichi Torii's paper (Astrophys.J. 597 (2003) L101-L106).

* GSC 3646-01698

We discovered a star with large proper mition of 0.5415 arcsec/year. It has been missed because it was blended with another star on Palomar plates around 1950.
See also Large proper motion of GSC 3646-01698.

* NSV 24062 = V4683 Sgr

Symbiotic star NSV 24062 discovered by Yukio Sakurai in 1994 was recovered. The star discovered by the MISAO Project as one of the new variable stars was identified with NSV 24062 by Taichi Kato. The position in IAUC 6051 was inaccurate about 15 arcsec. Hitoshi Yamaoka reported that a star found on DSS images at the MISAO's position, but none found at the IAUC 6051's position.
See also Recovery of NSV 24062.

* TmzV868

Kesao Takamizawa, the discoverer of TmzV868, announced it as a possible Mira type star. But Nikolai N. Samus pointed out that the type is different. Photometry from Nobuo Ohkura's images in the course of the MISAO Project supports that TmzV868 is not a Mira type variable.
TmzV868 is not a red star, but systematic difference of magnitude between the reflector and camera lens is found. The reason is still uncertain.
See also Photometry of TmzV868.

* MisV0001 = V4652 Sgr

Discovered from the observations of V4334 Sgr (Sakurai's object).
Seiichiro Kiyota reported Rc-band CCD observations. The light curve suggests that MisV0001 is a Mira type variable star with a period of about 390 days. One of the peak was around 2451280 (JD).
Taichi Kato reported that MisV0001 was about 16 mag on V-band image taken by Kyoto University Ouda team in 1996 March. Masayuki Suzuki also reported that MisV0001 is found on the Real Sky image taken on May 3, 1987, as a very faint star.

* MisV0002 = V523 Aur

Discovered from the observations of Comet 52P/Harrington-Abell. The comet was at apogee when brightest in 1998 December. Stars near by the comet were observed in details by chance, and the variation of MisV0002 was discovered.
Kazuhiro Nakajima's observations revealed it is a W UMa-type (EW) eclipsing variable with a period of 0.3303555 days, brightness range of 1.0 mag.
See also V523 Aur = MisV0002 is a W UMa-type eclipsing variable.

* MisV0005 = V2586 Oph

Taichi Kato identified with V854 Oph. We thought that V854 Oph was originally identified with the emission-line star Stephenson No.141 by Stephenson, but it is probably erroneous (IBVS 4843).
However, Nikolai N. Samus revealed that the identification of MisV0005 and V854 Oph is erroneous and MisV0005 is a new variable star [vsnet-chat 4071].

* MisV0015

John Greaves identified with OGLE2-BUL-SC22-V383.
The variation range from OGLE's I-band observations is small as 11.838 - 11.933 mag, although the range from MISAO's unfiltered CCD observations is large as 12.8 - 14.3 mag.
The OGLE-II light curve looks similar to those of GCAS stars. A GCAS star should be B type, however, the 2MASS J-Ks color of MisV0015 is so large as 1.303 mag.
See also Light Curve Analysis of MisV Stars Identified with Candidate Variable Stars from OGLE-II Bulge Data.
Further researches revealed that identification of MisV0015 with USNO-1.0 0525.24950305 was wrong. There is no identification in USNO-A1.0 at the corrected position measured from Ken-ichi Kadota's images. At the same time, identification with OGLE2-BUL-SC22-V383 was also wrong. Based on the corrected position, MisV0015 is identified with a Mira type variable with a period of 217 days, OGLE2-BUL-SC22-V384.

* MisV0047 = V4690 Sgr

John Greaves pointed out the possible identification with an X-ray star 1RXS J180000.7-293416. But it is a normal Mira type variable because bright in the 2MASS images.

* MisV0055 = V5534 Sgr

Taichi Kato identified with CD-27.12786 (9.8 mag). Kato commented that it may be a recovery of one of the missing CD stars. Such a bright star is not recorded in the GSC. Maybe the star was in outburst by chance when the CD catalog was compiled. However, there are many CD stars whose position is erroneous.
It is a normal Mira type variable because bright in the 2MASS images. It is not detected by the ASAS, so it is always fainter than 14 mag in V-band. So it is not likely that MisV0055 brightened up to 9.8 mag.

* MisV0106 = V2249 Cyg

Taichi Kato identified with NSV 25425. Kato revealed that Margoni and Stagni used blue photographic plate for the finding chart and labelled the wrong star (IBVS 4792).

* MisV0128 = V1464 Cyg

Identified with LD 183. And Williams identified LD 183 with V1464 Cyg.

* MisV0130

Identified with HS 1332. Because the policy on new variable stars was not established at the discovery, we assigned the MisV number for this star despite of the identification.

* MisV0134

Taichi Kato identified with NSV 11661. We reported MisV0134 as one of the new variable stars because it is 103 arcsec from NSV 11661. However, Kato revealed that the MisV0134 was marked as NSV 11661 (S9039 in the original paper) on the Hoffmeister's discovery chart. So the cataloged R.A. and Decl. of NSV 11661 was very erroneous.
Kato also pointed out that it is in the transition between a red variable star and a planetary nebula based on the IRAS data.
See also Identification of NSV 11661 with MisV0134: A possible post-AGB variable.

* MisV0149 = V2225 Cyg

John Greaves identified with ISV1956+29 discovered by Iida.

* MisV0187

John Greaves pointed out the identification with AC2000 383539. AC2000 383539 is bright as 11.8 mag (B), but not recorded in any of Hipparcos Input Catalog, Tycho Catalog, GSC. So MisV0187 may be a cataclysmic variable and was in outburst by chance on the AC2000 plate in 1920.
However, Seiichi Yoshida investigated the DSS 2 R-band image and revealed that there are two stars with the same magnitude with 6-7 arcsec distance in the east-west direction at the position of MisV0187, one is MisV0187 and another is AC2000 383539. So they are not the same. Only AC2000 383539 is found on the DSS 2 Bj-band image, so MisV0187 is probably a red variable.

* MisV0200 = V1552 Aql

Photographic observations were reported from Kesao Takamizawa and Katsumi Haseda [vsnet-newvar 1194], [vsnet-newvar 1196]. The light curve suggests that MisV0200 is a Mira type variable star with a period of about 350 days. One of the peak was around 2452205 (JD).
Takamizawa reported in [vsnet-newvar 1194] that the period is about 340 days, but period of about 350 days seems to fit the observations better. Observations by the MISAO Project were at faint phases when photographic brightness is fainter than 13.5 mag, so the unfiltered CCD peak brightness seems to be much brighter than 11 mag.

* MisV0297 = V364 Ser

Taichi Kato pointed out the possible identification with DZ Ser, a nova in 1960. Kato commented that DZ Ser is a 14-mag nova discovered in spectral observations. The position is very different on some papers as follows. 

  Duerbeck             175812.72 -103350.35 (1950.0)
  Wyckoff and Wehinger 175812.8  -103400.5  (1950.0)

However, Seiichi Yoshida revealed that it is found as a faint star on the DSS 1 and DSS 2 images, and it looks brighter on R-band image. So it will be a red variable.

* MisV0303

Revealed as Mira type by Patrick Wils's research.

* MisV0368 = V2271 Cyg

The NSVS data revealed that it is a semi regular variable with a range of 12.7 - 13.5 mag, and a period of 100 days. The unfiltered CCD observations from 1999 to 2000 by Ken-ichi Kadota and Nobuo Ohkura coincided to the magnitude range and the period.
However, it was observed as 15.4 mag, much fainter than the range, in the course of the unfiltered CCD observations by Nobuo Ohkura using a 300-mm camera lens in 2003 September. It is uncertain if the star really faded drastically, or that is an effect of came lens characteristics.

* MisV0372 = V5382 Sgr

Taichi Kato and John Greaves pointed out the possible identification with an X-ray star 1RXP J180245-2942.3. But it is revealed to be a normal Mira type variable based on the OGLE-II data.

* MisV0380

Seiichi Yoshida and John Greaves found that it is not recorded in any of GSC 1.1, USNO-A2.0, IRAS, 2MASS, UCAC1, GSC 2.2. Greaves investigated the past images at the USNO Flagstaff Station Integrated Image and Catalogue Archive Service, but no star was found within 3 arcsec. It implies the star may be a cataclysmic variable. So Greaves called for observations in the MSDG-MISAO Campaign.
Mike Simonsen, Rod Stubbings and C. P. Jones reported that is was fainter than 14.2 mag visually. But it was bright as 12.39 mag on the unfiltered CCD image taken by Fred Velthuis. In addition, Taichi Kato identified with MSX5C G011.9229+03.4421. Therefore, it is probably a Mira-type variable.
Yoshida revealed that no star is found at the position on the DSS 1 Bj-band image. There are two DSS 2 R-band images. A star is found on one of them, but not uncertain on another image. Due to the high density of stars, past image investigation was hard.

* MisV0395

Taichi Kato revealed that it was observed as NGC 6194 No. 1130 and is a red star.

* MisV0508 = V949 Sgr

Taichi Kato identified with V949 Sgr, a nova in 1914. MISAO's observations, followed by Patric Schmeer's observations, revealed that it is not a nova but a red variable (IBVS 4845).

* MisV0525 = V1694 Aql

John Greaves pointed out the possible identification with an X-ray star 2RXP J193158.1110964. But it is a normal Mira type variable because bright in the 2MASS images.

* MisV0562

Mati Morel pointed out the possible identification with Luyten's V915 Sgr. The range by Luyten (12.3-13.5p) is not too dissimilar to that of MisV0562 (11.8-13.8C). V915 Sgr is regarded as GSC 6870-00090 in Herbig's paper (PASP 70,605) and classified as RCB type with a period of 285.2 days, which can well refer to the period of MisV0562. If MisV0562 is V915 Sgr, it turns out to be a SR variable [vsnet-chat 2797].
However, the variability of V915 Sgr = GSC 6870-00090 was also detected in the MISAO Project. So MisV0562 is a new variable star [vsnet-chat 2803].

* MisV0645

Taichi Kato pointed out that KY Sgr, a nova in 1926, is close, 126 arcsec from MisV0645.
However, Seiichi Yoshida found it on the DSS 1 and DSS 2 images, so it will not be a cataclysmic variable. But it looks brighter on Bj-band image than on R-band image.

* MisV0665 = V5542 Sgr

Kazuhiro Nakajima's observations revealed it is an Algol-type (EA) eclipsing variable with unfiltered CCD variations of 13.18 mag at maximum, 13.84 mag at primary minimum, 13.26 mag at secondary minimum, and period of 1.6351 days (IBVS 5500).
See also MisV0665 is an Algol-type eclipsing variable.

* MisV0694

John Greaves identified with ROTSE1 J185841.70+302042.8. ROTSE's observations revealed that is is a long periodic variable.

* MisV0701 = V1511 Aql

Taichi Kato pointed out that it is near by a planetary nebula PK 32-3.1 and influenced to the past observations of PK 32-3.1.
MISAO's observations, followed by TASS's observations, revealed that MisV0701 is a red variable.
In the past papers (Stenholm & Acker, MacConnell), PK 32-3.1 was noted that maybe it is not a planetary nebula because the spectrum was that of a red variable. But the spectrum was probably the mixture with a red variable MisV0701. The IRAS data is on the border between a planetary nebula and a red variable. That is probably the mixture of the two objects' characteristics, too.
See also Influence of MisV0701 to a planetary nebula PK 32-3.1.

* MisV0719 = V418 Vul

This star is near by M27, so Gianluca Masi had noticed the variability and recorded in his WWW page.

* MisV0774 = V559 Cyg

John Greaves reported that the position of V559 Cyg was revised in IBVS 4905 and came to coincide with MisV0774.

* MisV0779 = V1229 Cyg

John Greaves reported that the position of V1229 Cyg was revised in IBVS 4799 and came to coincide with MisV0779.

* MisV0814

Identified with 2MASS 0533337+344323. The 2MASS J-Ks value is 0.384 mag, so it is not a red variable.
Masayuki Suzuki pointed out that the data in the USNO catalog is very reddish, 13.0 mag (R) and B-R=+4.0, but the USNO magnitude is uncertain. That is probably the influence of the very bright nearby star.
Kazuhiro Nakajima revealed that MisV0814 is probably a peculiar variable, which is usually constant, but rarely shows minute-scale rapid variations.
See also Peculiar variation of MisV0814.

* MisV0855 = V4656 Sgr

A very faint red variable in very crowded field. The USNO-A2.0 shows the color as B-R=4.0 mag. John Greaves commented that the star is only found on red E plate, and not found on blue O plate, though both plates were on the same day, which suggests this star is very red.
On the MISAO images, the position of MisV0855 looks slightly different between in bright and faint state at a glance. That is because MisV0855 is not visible when it becomes faint, instead only a star about 10 arcsec southeast of MisV0855 is visible.

* MisV0884

When it was bright as 9.3 mag in the MISAO Project observations, Guy M Hurst and Mike Collins reported that MisV0884 was too faint, fainter than 11 mag. Hurst's observations are unfiltered CCD, as same as the MISAO observations.

* MisV0898

Identified with 2MASS 1800214-304831, (J=10.764 mag, J-Ks=0.739 mag. It is probably not a red variable because of the small J-Ks value. Seiichi Yoshida revealed that it is clearly found on the DSS 2 R-band and Bj-band images, which also implies that it is not a red variable.
However, Yoshida and John Greaves found that it is not recorded in any of GSC 1.1, USNO-A2.0, IRAS, 2MASS, UCAC1, GSC 2.2, despite of the bright peak magntiude (11.6 mag).
However, further research revealed that it is recorded in USNO-A2.0 and USNO-B1.0. The R.A. and Decl. was inaccurate.

* MisV0909, MisV0910

A pair of double variable stars with 19 arcsec distance.

* MisV0949 = V659 Aql

John Greaves reported that the position of V659 Aql was revised in the latest online edition of the GCVS and came to coincide with MisV0949.

* MisV0968 = V423 Vul

John Greaves identified with one of the binary WDS 19277+2423 = Pourteau 3835, the pair of 13.6 mag and 13.8 mag stars. The cataloged position of WDS 19277+2423 is 48 arcsec from MisV0968. But the separation and position angle of MisV0968 and a nearby star USNO-A2.0 1125.12713797 is 9.8 arcsec in 111 degree, which correspond to those of WDS 19277+2423, 9.2 arcsec in 115 degree very well. Greaves commented that Pourteau 3835B is probably MisV0968 because the position well coincides with that of IRAS, 2MASS, MSX5C data.

* MisV1023 = V1462 Cyg

In 2000, when the position of V1462 Cyg was inaccurate, we the MISAO Project discovered two new variable stars around it. One of them is identified with NSV 12600. We thought V1462 Cyg ans NSV 12600 are the same star (IBVS 4814), and announced another star as a new variable star MisV1023.
In 2003, the GCVS editors revised the position of V1462 Cyg (2003AstL...29..468S). The revised position is different from NSV 12600, but same as MisV1023. Therefore, it was revealed that MisV1023 was not a new variable.

* MisV1024

Because it is identified with IRAS 19596+3350 and an S-type star NSS 49, it is probably a red variable. But the 2MASS magnitude is J=7.312 mag, J-Ks=0.729 mag, so the J-Ks value is fairly small as a red variable.
Brian Skiff commented that the 2MASS J-Ks value may be erroneous, probably because of saturation or errors in the data-reduction.

* MisV1051

John Greaves pointed out the possible identification with an X-ray star 1RXS 201351.8+414557. However, Taichi Kato pointed out that a bright star GSC 3159.1639 is closer to the X-ray star and that will be identified with it. So MisV1051 and 1RXS 201351.8+414557 are not the same.

* MisV1061 = V456 Vul

Kazuhiro Nakajima's observations revealed it is an Algol-type (EA) eclipsing variable with V-band variations of 12.14 mag at maximum, 12.81 mag at primary minimum, 12.55 mag at secondary minimum, and period of 3.0421 days (IBVS 5600).
See also MisV1061 is an Algol-type eclipsing variable.

* MisV1073

John Greaves pointed out that there is an X-ray star 1RXS 200142.7+465727 about 1 arcmin south of MisV1073. But they are probably not the same because of the large distance.

* MisV1095 = V440 And

Kazuhiro Nakajima's observations revealed it is an Algol-type (EA) eclipsing variable with unfiltered CCD variations of 12.64 mag at maximum, 13.24 mag at primary minimum, 12.90 mag at secondary minimum, and period of 1.5829 days (IBVS 5600).
Times of minima observed by Ondrej Pejcha are published in the IBVS paper (IBVS 5645).
Osamu Ohshima caught the eclipse in 2008 January, and the ephemeris of elicpses are updated precisely with Kazuhiro Nakajima's observations in 2003 and further observations in Europe.
See also MisV1095 is an Algol-type eclipsing variable.
John Greaves pointed out that the USNO-B1.0 color is so red as B1-R1=2.9 mag, which suggests the spectral class is K or M type. However, Seiichi Yoshida pointed out that the USNO-A2.0 color is so blue as B-R=0.3 mag. And the 2MASS color is J-Ks=0.759 mag, intermediate between blue and red.
Therefore, it was suspected to change its color in the eclipse. However, no remarkable color change between normal phase and eclipse phase was observed by Osamu Ohshima's observations. The USNO-B1.0 color seems to erroneous.

* MisV1096 = V441 And

Kazuhiro Nakajima's observations revealed that it is a W UMa-type (EW) eclipsing variable with unfiltered CCD variations between 13.48 mag and 14.25 mag, and period of 0.4696 days (IBVS 5600). The brightness at primary minimum and secondary minimum is almost same.
See also MisV1096 is a W UMa-type eclipsing variable.

* MisV1097 = V444 And

Ondrej Pejcha revealed it is a W UMa-type (EW) eclipsing variable. It is probably a blue one (EW/KE type), the minority among them.
See also MisV1097 is a blue W UMa-type eclipsing variable.
Kazuhiro Nakajima's observations revealed the unfiltered CCD variations between 13.04 and 13.74 mag, and period of 0.4688 days (IBVS 5600).
Times of minima observed by Ondrej Pejcha are published in the IBVS paper (IBVS 5645).
See also Times of minima of a W UMa-type eclipsing variable MisV1097.

* MisV1105 = V2421 Cyg

Kazuhiro Nakajima's observations revealed it is a beta Lyr-type (EB) eclipsing variable with unfiltered CCD variations of 13.79 mag at maximum, 15.03 mag at primary minimum, 14.20 mag at secondary minimum, and period of 0.6331 days (IBVS 5600).
See also MisV1105 is a beta Lyr-type eclipsing variable.

* MisV1140 = V450 Lac

It was presumed as an eclipsing variable with large amptitude of almost 2 mag at the discovery. John Greaves commented that if MisV1140 is an Algol-like eclipsing variable, the primary may be an A star and the secondary may be a K star, for the large amplitude.
Hitoshi Yamaoka pointed out the possible identification with an eclipsing variable GH Lac. The position of GH Lac is revised in IBVS 4906, identified with a star 3.2 arcmin from the position in the GCVS 4.1. But no basis is described in the paper. MisV1140 is 7 arcmin from the position in the GCVS 4.1.
GH Lac was observed at Brno Observatory based on IBVS 4906 and the eclipsing variation was confirmed (IBVS 5263). Miloslav Zejda and Ondrej Pejcha measured MisV1140's brightness on those GH Lac images, and confirmed the variation of 1.1 mag. So MisV1140 and GH Lac are confirmed to be different objects.
John Greaves pointed out that USNO-B1.0 B1-R1 value is 1.7 mag, so B-V may be around 0.8 - 0.9 mag. He also pointed out that it is within a dark cloud IREC 130 (diameter 106') and reddened about 0.16 mag.
Kazuhiro Nakajima's observations revealed it is an Algol-type (EA) eclipsing variable with unfiltered CCD variations of 13.50 mag at maximum, 14.8 mag at primary minimum, 13.68 mag at secondary minimum, and period of 4.4479 days (IBVS 5600).
See also MisV1140 is an Algol-type eclipsing variable.

* MisV1147 = V730 Cep

It attracted attention due to the identification with a H-alpha emission star HBHA 65-53. The campaign in "vsnet-campaign-unknown" and the MSDG observing campaign were launched, and many visual observers have been monitoring it. It did not show any evident variation in the first half of 2002, however, it showed frequent deep eclipse-like fadings in the latter half of the year. Based on the spectrums taken by Kenzo Kinugasa and Mitsugu Fujii, Taichi Kato revealed MisV1147 is a young stellar object, a Herbig Ae/Be type star.
See also MisV1147: Young Stellar Object.
Makoto Uemura, et al., revealed that MisV1147 has one of the largest amplitudes of variations among Herbig Ae/Be stars, and MisV1147 is peculiar which breaks the relation between the variation amplitude and the spectral type of Herbig Ae/Be stars (PASJ: Publ. Astron. Soc. Japan 56, S183-S192).

* MisV1181 = V709 Cep

We discovered a nova, which had been missed in 2001, in 2002. It was 12.7 mag in 2001 September, 14.3 mag in November, but faded to 20 mag in 2002 October. It was not found in any past Palomar plates nor DSS images.
It took some time to be regarded as a nova, because IRAS 22562+6606 exists closly, and one of the Palomar plate images was erroneous.
This nova was announced in IAUC 8014.

* MisV1202 = V728 Cep

John Greaves pointed out that MisV1202 lies within/behind bright emission nebula Sharpless 134.

* MisV1220 = V452 And

Kazuhiro Nakajima's observations revealed it is a beta Lyr-type (EB) eclipsing variable with unfiltered CCD variations of 13.80 mag at maximum, 15.14 mag at primary minimum, 14.04 mag at secondary minimum, and period of 0.9784 days (IBVS 5600).

* MisV1222 = V1001 Cas

See also New beta Lyr-type eclipsing variable MisV1222.
Kazuo Nagai pointed out that it may be EA/RS type, a rare eclipsing variable with distortion wave outside eclipses. But the distortion in the light curve of MisV1222 is probably due to errors.

* MisV1223 = MN Cam

Patrick Wils and John Greaves revealed that it is a Cepheid variable with a period of 8.2 days from the NSVS data (IBVS 5512).
Based on the V-band survey from Oct. 25 to Dec. 7 in 2003, and Rc-band survey from Sept. 30 to Dec. 14 in 2004 by Nobuo Ohkura, the light curve is obtained and it was confirmed to be a Cepheid variable with a period of 8.2 days. The magnitude ranges are revealed to be 11.99-12.51 mag in V-band, and 11.20-11.80 mag in Rc-band.
Toshihito Ishida commented that this star belongs to a group named bump Cepheid, a Cepheid variable with a bump in its light curve.

* MisV1224 = MQ Cam

Patrick Wils and John Greaves revealed that it is a Cepheid variable with a period of 6.60 days from the NSVS data (IBVS 5512).
Based on the V-band survey from Oct. 25 to Dec. 7 in 2003, and Rc-band survey from Sept. 30 to Dec. 14 in 2004 by Nobuo Ohkura, the light curve is obtained and it was confirmed to be a Cepheid variable with a period of 6.60 days. The magnitude ranges are revealed to be 12.69-13.31 mag in V-band, and 11.96-12.68 mag in Rc-band.

* MisV1225 = MP Cam

Kazuhiro Nakajima's observations revealed it is a beta Lyr-type (EB) eclipsing variable with unfiltered CCD variations of 12.68 mag at maximum, 14.04 mag at primary minimum, 13.19 mag at secondary minimum, and period of 2.6092 days (IBVS 5600).

* MisV1226 = MT Cam

Kazuhiro Nakajima's observations revealed it is a W UMa-type (EW) eclipsing variable with unfiltered CCD variations of 12.94 mag at maximum, 13.54 mag at primary minimum, 13.50 mag at secondary minimum, and period of 0.3662 days (IBVS 5600).

* MisV1227 = V962 Cas

Kazuhiro Nakajima's observations revealed it is an Algol-type (EA) eclipsing variable with unfiltered CCD variations of 12.93 mag at maximum, 13.51 mag at primary minimum, 13.41 mag at secondary minimum, and period of 2.7129 days (IBVS 5600).

* MisV1228 = V727 Cep

Kazuhiro Nakajima's observations revealed it is an Algol-type (EA) eclipsing variable with unfiltered CCD variations of 14.15 mag at maximum, 14.53 mag at primary minimum, 14.48 mag at secondary minimum, and period of 6.6490 days (IBVS 5700).

* MisV1237

Kazuhiro Nakajima's observations revealed it is an Algol-type (EA) eclipsing variable with unfiltered CCD variations of 13.34 mag at maximum, 13.94 mag at primary minimum, 13.90 mag at secondary minimum, and period of 7.5530 days (IBVS 5700).
Our second eccentric binary. The secondary minimum occurs at the phase of 0.484.

* MisV1239 = V959 Cas

Kazuhiro Nakajima's observations revealed it is a W UMa-type eclipsing variable with unfiltered CCD variations of 11.97 mag at maximum, 12.61 mag at primary minimum, 12.47 mag at secondary minimum, and period of 1.0650 days (IBVS 5600).
See also New W UMa-type eclipsing variable MisV1239.

* MisV1262

It was announced as a possible semi-regular variable with a small amplitude at the discovery. But further observations revealed it is a Mira type variable with large amplitude.
Unexpectedly, V-band observations caught a 14.9 mag star at the position of MisV1262, when it faded down to 14.1 mag by unfiltered CCD observations. It was almost constant in V-band.
Investigating DSS images and USNO-B1.0 catalog revealed that there is a complex of three stars within 15 arcsec at the position of MisV1262, and a nearby star becomes brighter than MisV1262 in B-band and V-band. A 14.9 mag star in V-band images must be the nearby star.
The NSVS light curve also shows a rough variation of this star with a range of 12.8 - 14.1 mag. However, the NSVS data must be blending of the complex, and must not show the total variation.
See also Complex Around a Mira Type Variable MisV1262.

* MisV1267

MisV1267 is recorded in the Hamburg-Bergedorf H-alpha Stars in Northern Milky Way as HBHA 18-40. Only two stars, among 1375 MISAO Project new variable stars, are identified with H-alpha emission stars. One is MisV1147 = V730 Cep, a peculiar Herbig Be star. Another one is MisV1267.
MisV1267 is also recorded in the carbon star catalogs as CGCS 719 = CGCS J0435+5250. Therefore it is a carbon star with H-alpha emission.
The MISAO Project observations suggest that MisV1267 is a Mira type variable with a period of about 400 days. The NSVS light curve shows a peculiar stagnation of brightening. The MISAO Project observations also suggest a hint of the stagnation.
Brian Skiff commented that H-alpha emission is kinda the usual thing for cool carbon stars. Brian Skiff also pointed out that MisV1267 is identified with a carbon star Kiso C5-213, and an emission line star VES 820.

* MisV1268

John Greaves researched the NSVS data and confirmed the RR type variation between 13.5 - 14.3 mag with a period of 0.564 days.

* MisV1269

John Greaves found it may be variable while researching the NSVS data. Seiichi Yoshida confirmed this is indeed variable, and a new variable star, from images taken by Nobuo Ohkura, and announced it as one of the MISAO Project new variable stars.

* MisV1275

Kazuhiro Nakajima's observations revealed it is an Algol-type (EA) eclipsing variable with unfiltered CCD variations of 12.25 mag at maximum, 12.97 mag at primary minimum, 12.87 mag at secondary minimum, and period of 4.6050 days (IBVS 5700).

* MisV1276

Patrick Wils researched the NSVS data and found that it is an EA type star with a period of 1.2727 days (or double).

* MisV1277

Patrick Wils researched the NSVS data and found that it is a Cepheid type variable with a period of 4.24(7) days.

* MisV1278

Patrick Wils researched the NSVS data and commented that MisV1278 has a small range 12.6-12.8, and a possible frequency of 2.787 cycles/day, or an alias thereof, but because of the small range, it is doubtful.
Kazuhiro Nakajima's observations revealed it is an Algol-type (EA) eclipsing variable with unfiltered CCD variations of 13.35 mag at maximum, 13.82 mag at primary minimum, 13.77 mag at secondary minimum, and period of 1.1205 days (IBVS 5700).

* MisV1282

John Greaves researched the NSVS data and found that it is a Mira type variable with a period of 170 days.

* MisV1286

It may be identified with NSV 11227 whose position is uncertain.
If NSV 11227 is a red variable, an IRAS or MSX5C object near by the catalogued position is likely a candidate of identification. But there is none around the position. In the 2MASS images, there are three bright stars exist about 1 arcmin from NSV 11227 forming a triangle. The catalogued position of NSV 11227 is at the center of the triangle, so one of them may be identified with NSV 11227. MisV1286 is one of the three stars.

* MisV1287

Kazuhiro Nakajima's observations revealed it is a beta Lyr-type eclipsing variable with unfiltered CCD variations between 12.25 and 12.78 magnitude, and period of 0.7655 days (IBVS 5700).

* MisV1288

* MisV1291

Kazuhiro Nakajima's observations revealed it is a beta Lyr-type eclipsing variable with unfiltered CCD variations between 12.68 and 13.15 magnitude, and period of 1.0996 days (IBVS 5700).

* MisV1295

Kazuhiro Nakajima's observations revealed it is an Algol-type eclipsing variable with unfiltered CCD variations between 12.98 and 13.73 magnitude, and period of 2.2002 days (IBVS 5700).

* MisV1296

Kazuhiro Nakajima's observations revealed it is an Algol-type eclipsing variable with unfiltered CCD variations between 13.61 and 14.89 magnitude, and period of 5.2633 days (IBVS 5700).

* MisV1306

Kazuhiro Nakajima's observations revealed it is an Algol-type eclipsing variable with unfiltered CCD variations between 11.97 and 12.50 magnitude, and period of 5.3364 days (IBVS 5700).
Unusual eccentric binary. The secondary minimum occurs at the phase of 0.412.
Michael Sallman reported that TASS caught this one in primary eclipse twice, on JD 2452911.80072 and 2453322.67412 (light curve).
See also MisV1306: New Eccentric Binary.

* MisV1313

Kazuhiro Nakajima's observations revealed it is an Algol-type eclipsing variable with unfiltered CCD variations between 14.65 and 16.18 magnitude, and period of 4.5899 days (IBVS 5700).

* MisV1317

Kazuhiro Nakajima's observations revealed it is a beta Lyr-type (EB) eclipsing variable with unfiltered CCD variations of 11.90 mag at maximum, 12.70 mag at primary minimum, 12.12 mag at secondary minimum, and period of 1.28482 days (IBVS 5700).
Atsushi Miyashita caught the primary eclipse on 2008 Feb. 21 and confirmed that the ephemeris error is less than 5 minutes.

* MisV1325

Observations by Kazuhiro Nakajima, and the NSVS data suggest that MisV1325 is almost constant at about 14.2 mag. Observations by Nobuo Ohkura and Youichirou Nakashima also suggest that it keeps almost constant at 13.5-13.8 mag from 2001 to 2007, however, it faded only in 2000 and became fainter than 14 mag. So MisV1325 may be a RCB type variable, which rarely fades out.
Nakajima's observations and the NSVS data also suggest the small variation with an amplitude of about 0.2 mag in its normal state.

* MisV1327

Kazuhiro Nakajima's observations revealed it is a RRAB type variable with unfiltered CCD variations between 13.85 and 14.80 magnitude, and period of 0.53201 days (IBVS 5700).

* MisV1329

Kazuhiro Nakajima's observations revealed it is an Algol-type eclipsing variable with unfiltered CCD variations between 13.82 and 14.80 magnitude, and period of 4.9478 days (IBVS 5700).

* MisV1330

Kazuhiro Nakajima's observations revealed it is an Algol-type eclipsing variable with unfiltered CCD variations between 14.22 and 14.71 magnitude, and period of 2.8610 days (IBVS 5700).

* MisV1331

Kazuhiro Nakajima's observations revealed it is a beta Lyr-type (EB) eclipsing variable with unfiltered CCD variations of 14.40 mag at maximum, 15.10 mag at primary minimum, 14.80 mag at secondary minimum, and period of 2.8271 days (IBVS 5700).

* MisV1332

Kazuhiro Nakajima's observations revealed it is an Algol-type eclipsing variable with unfiltered CCD variations between 13.74 and 15.14 magnitude, and period of 2.6525 days (IBVS 5700).

* MisV1333

The variation of this star was discovered in 1999 September in the course of the MISAO Project. But we regarded it as DV Oph because it was only 2.1 arcmin from the catalogued position of DV Oph [vsnet-id 111].
However, it was revealed that the semi regular variation of the star at the catalogued position of DV Oph ( ASAS 165756-2411.3 ) is clearly detected by the ASAS-3 data. Therefore, the variable star discovered by the MISAO Project was revealed to be a new object.
Both DV Oph and MisV1333 are red variables. DV Oph is detected as 12.1-13.7 mag in the ASAS-3 data, but MisV1333 is not detected, fainter than 14 mag. That means DV Oph is brighter in V-band. On the other hand, MisV1333 looks much brighter than DV Oph in the 2MASS images. Therefore, MisV1333 is much more reddish than DV Oph, intense in infrared.

* MisV1336

Discovered during time series photometry of MisV1275.
The light curve suggests it is a bright irregular variable with an average magnitude of 11.5 mag and a small amplitude of 0.42 mag.
Not only the long term irregular variation, a short term small variation of 0.1 mag during several hours was also confirmed by the time series photometry on three nights.
There are two entries in the NSVS catalog. The NSVS data suggests it is completely constant at 11.60 mag. No variation over 0.1 mag was not recorded in 1999, which suggests MisV1336 is not a periodic variable. But the NSVS data must be blending with a southern star with similar brightness.
Michael Richmond researched the TASS Mark IV database and found no significant variation in either V or I band (light curve). The mean color is (V-I) = 0.52. Note that the TASS Mark IV data is also blending.

* MisV1337

Kazuhiro Nakajima's observations revealed it is a beta Lyr-type (EB) eclipsing variable with unfiltered CCD variations of 12.58 mag at maximum, 13.55 mag at primary minimum, 13.01 mag at secondary minimum, and period of 0.9202 days (IBVS 5700).

* MisV1339

Discovered during time series photometry of MisV1317.
The light curve suggests it is a semi regular variable with an unfiltered CCD amplitude of 0.25 mag between 10.02 - 10.27 mag.
Not only the long term variation, a short term oscillation with an amplitude of 0.10 mag was also confirmed by the time series photometry on three nights in the course of Kazuhiro Nakajima's observations.
MisV1339 is almost constant at 10.323 +/- 0.022 mag in the NSVS data.
Michael Richmond researched the TASS Mark IV database and found one feature in the I-band, but otherwise no obvious variations was found (light curve). The mean color is (V-I) = 0.79.
Mitsugu Fujii's spectrum on 2008 Mar. 5 (the red is MisV1339) is a normal spectrum of a G-type star.

* MisV1340

New Mira type variable adjoining to a Mira type variable V2010 Cyg = LD 162. MisV1340 is a northern component of double stars with similar brightness lying north-south direction with a separation of 20 arcsec, and the southern component is V2010 Cyg.
We once judged the identification of V2010 Cyg was wrong and reported it as the revision of V2010 Cyg's coordinates [vsnet-id 299]. Afterward, we concluded both of the double stars are variable and announced the northern star as a new variable.
See also Mira Variable V2010 Cyg and Another Adjoining New Mira Variable MisV1340.

* MisV1344

The NSVS data suggests it is a Mira type variable with a period of about 300 days and the epoch of JD = 2451370.

* MisV1347

The NSVS data suggests it is a Mira type variable, although the period is not determined.

* MisV1351

An Algol-type eclipsing variable. However, only two eclipsing events were detected on 164 nights during three years by Kazuhiro Nakajima. So the eclipse of MisV1351 must be very rare.
Sebastian Otero researched the NSVS 8483544 and NSVS 8463372 data. But these NSVS stars are not MisV1351, about 1 arcmin north and south of MisV1351. Although a possible period of 3.69764 days was derrived based on the NSVS data, it must be false due to the erroneous data. Sebastian Otero pointed that MisV1351 was not measured by the TASS.
Sebastian Otero pointed out that the 2MASS color is J-K = 0.91, very red. If MisV1351 is a long period eclipser, it is probably an EA/GS system.

* MisV1354

It was already found by Patrick Wils and solved by Sebastian Otero to be an EA eclipser with a period of 6.9092 days using the NSVS data, and published in IBVS 5681. Actually, it is not a new variable star of the MISAO Project.

* MisV1355

Although it had been almost constant during two months in 2001, the light curve during two months between 2006 and 2007 looks like a long term variation. The light curve and the USNO-A2.0 color suggests it is a red variable.

* MisV1360

The scattering in the NSVS data is very intense, which suggests that MisV1360 is a short periodic variable but not an eclipsing variable. However, any significant period cannot be determined using the phase dipersion minimization tool based on the NSVS data.

* MisV1376

Ken-ichi Kadota investigated the DSS images, and found that the DSS images revealed that two faint stars are blending on the Nobuo Ohkura and Youichirou Nakashima's images. The northern counterpart is clearly visible on the DSS Bj-band image in 1989, however, not visible on the B-band images in 1952 and 1954. It looks bright on the DSS R-band and I-band images.
The DSS images between 1989 and 1993, and the USNO-B1.0 data suggest no proper motion. So we concluded that MisV1376 is the northern counterpart, and is a red variable.

* MisV1384

Patrick Wils analyzed the NSVS data and revealed that MisV1384 seems to be an EA type variable with a period of 1.1609 days.

* MisV1385

Patrick Wils commented that it has been found before by Wils P., Lloyd C., Bernhard K. (MNRAS 368, 1757), RRAB type variable with a period of 0.47414 days (not 0.902 days).

* MisV1386

Patrick Wils analyzed the NSVS data and revealed that MisV1386 is an EW type star with a period of 0.3406 days. Kazuhiro Nakajima revised the accuracy of the period as 0.340533 days.

* MisV1387

Patrick Wils analyzed the NSVS data and revealed that MisV1387 is an EW type star with a period of 0.2628 days. Kazuhiro Nakajima revised the accuracy of the period as 0.263002 days.

* MisV1396

The USNO-A2.0 color is B-R = -0.4 mag. The RGB composite image from DSS I, R and Bj images also suggests that MisV1396 is remarkably blue.
MisV1396 faded only once by the MISAO Project observations. It is almost constant the other days. The NSVS light curve shows MisV1396 is almost constant, or maybe it shows a small irregular variation.
But Arne Henden revealed it is not so blue, as the TASS color is (V-Ic) = 0.41, the Tycho color is (B-V) = 0.275, and the 2MASS color is J=10.704, H=10.662, K=10.592.

* MisV1436 = QSO B0133+47

We discovered a quasar QSO B0133+47 brightened up to 14 mag in 2007 November. It is recorded as 18-19 mag in the catalogs, so it is revealed to be an optically violently variable QSO. Taichi Kato commented that a quasar with such a large amplitude is rare. Well researched in the radio observations, however, little observed optically. Nobody has noticed that this quasar becomes so bright. It is about 7 billion light years from our planet, and the apparent brightness of 14 mag is extraordinary at this distance.
In the DSS plates, it has been so faint as around 18 mag until 1992, but small outbursts have occurred twice in 1993 and 1995. However, it is much brighter than any past DSS plates in the MISAO Project CCD images on 2007 November 11.
John Greaves pointed out that it is recorded bright as 14.3 mag and 15.0 mag in the UCAC2 and CMC14 catalogs. Both observations were in 2002. Reinder J. Bouma pointed out that it was recorded as 15.0 mag on 2002 Sept. 24 in the Skymorph archive.
No records brighter than 18 mag have been found before 1992, and no records fainter than 17 mag have been found after 1995. This quasar may became very active in recent years.
See also Discovery of optically violently variable quasar QSO B0133+47.

* MisV1439 = OT 081

Another optically violently variable quasar observed by the MISAO Project. But this is a well known quasar. We assigned the MisV number, but this is not our new discovery.
The outburst in 2007 observed by the MISAO Project has been already reported by Stefan Karge [vsnet-alert 9356], and published at Karge, S., 2007, The Astronomer, Vol. 44, No 520, 100.
Reinder J. Bouma searched the Skymorph archive and confirmed the clear variability of this object in 1997, 2002 and 2003.
See also Discovery of Another Optically Violently Variable Quasar 4C 09.57.

* MisV1441

Seiichi Yoshida, Patrick Wils and Taichi Kato identified it with an H-alpha emission source HBHA 50-20 = IPHAS J205050.39+445011.7.
Seiichi Yoshida investigated the 2MASS data, and found it is fairly faint in the J-band image, fainter than our unfiltered CCD images, although the color is very red and bright in the Ks-band image.
Taichi Kato also pointed out that it is in a star forming region SFR G85.49-1.00, and this star seems to be a T Tau variable (possibly INSB type).

* MisV1442

New eclipsing variable. Seiichi Yoshida found it is recorded in the LONEOS Photometry File "loneos.phot" as follows:

12.95(Ic) 13.57(Rc) 14.22(V) 15.28(B)
B-V=1.06 V-R=0.65 V-I=1.27
