MISAO Project

Japanese version       Updated on April 20, 2014

MISAO Project aims to make much use of images taken all over the world for searching and tracking astronomical remarkable objects.


    Feb. 16    MisV1341 is brightening rapidly.

Tsutomu Fujiwara's observations detected the rapid brightening up to 11.5 mag in February, although it kept almost constant at 12.3 mag for over one year from 2012 Novembet to 2014 January.

    Feb. 9    NSV 02026 is a very active dwarf nova.

Denis Denisenko pointed out it is a very active dwarf nova with a short outburst cycle, as the outburst occured within a month on 2013 Dec. 29 and 2014 Jan. 23. The outburst on Jan. 23 was also detected from Youichirou Nakashima's survey images at 14.4 mag.

    Jan. 19    Outburst of dwarf nova NS Per.

We detected that NS Per in outburst at 16.3 mag on Jan. 15 from Youichirou Nakashima's survey images. Maybe it brightens in outburst frequently in a short time.

    Jan. 13    Recent variation of optically violently variable quasar MisV1436 = QSO B0133+47.

Miguel Rodriguez Marco's observations between 2013 Sept. 29 and 2014 Jan. 2 are published, which show the variation around 17-18 mag.

    Please observe these stars!    

We the MISAO Project need the observations of following stars. If you observe these stars, please report to Seiichi Yoshida (comet@aerith.net).
If you have a plan to research these stars or write a paper on these stars, we the MISAO Project can offer you our data. Please make a contact to Seiichi Yoshida (comet@aerith.net).

o Long Periodic Variables Campaign

MISAO Project is operating a continuous observation campaign to obtain light curves and reveal the periods of long periodic variables discovered by the MISAO Project.

o Eclipsing Binaries / Short Periodic Variables Campaign

MISAO Project is operating a time series photometry campaign to obtain light curves and reveal the types and periods of new eclipsing binaries and short periodic variables discovered by the MISAO Project.

o MisV0814

Very peculiar variable. It keeps constant since 2008.

o MisV1336

Irregular variation of 0.4 mag in a long term, and a short term small variation of 0.1 mag during several hours, were observed. But no variation was detected by other surveys. Continuous monitoring is encouraged.

o MisV1339

It seems to be a popular semi regular variable in a long term. But a minute-scale short term oscillation of 0.1-0.3 mag was also observed a few times. Time series photometry is encouraged.

o MisV1436

Optically violently variable quasar QSO B0133+47. It is recorded as a very faint object at 18-19 mag in the 20th century. However, it was so bright as 14 mag in 2007 November. Then it faded down to 19.5 mag in 2012 January, faintest in its history. It had been fainter than 17 mag since 2010, however, it brightened up to 15.66 mag in 2013 February. Now it turns to be faint as 18 mag.

o MisV1441

T Tau type variable, a young stellar object with an H-alpha emission in a star forming region. It brightened rapidly and reached up to 14.66 mag in 2011 autumn. It keeps around 15.5 mag with only a small variation recently in 2012.

o MisV1443

Dwarf nova brightened up to 12.8 mag in 2011 January. It has already faded out, fainter than 18 mag.

o MisV1445

It brightened rapidly by 2 mag or more, from fainter than 16.8 mag up to 14.7 mag, withiin only 4 minutes on 2011 Dec. 17. It is possible real-time flare detection of a new flare star. It has already faded out, fainter than 18 mag.

o MisV1446

Bright new object of 14.1 mag discovered on Jan. 5, 2012. It will be an outburst of an X-ray source 1RXS J074112.2-094529. It has already faded out, fainter than 17.5 mag.

o MisV1448

Bright new dwarf nova brightened up to 12 mag on May 13, 2012. It has already faded out, fainter than 16 mag.

    CCD Images Invited    

MISAO Project inviting your CCD images contribution. The offered images are examined by the PIXY (Practical Image eXamination and Inner-objects Identification) system 2 developed in the MISAO Project and searched for new objects such as variable stars. The new objects will be reported to the public as collaborated discovery of the image contributors and the MISAO Project. The magnitude of known variable stars are also measured and reported as MISAO Project observations.

    Guide Books    

Here introduces some know-how of observations and surveys.

    Research Reports    

Here introduces interesting reports researched by the MISAO Project.

    Database & Service    

Here serves the image information in the MISAO Project database. The web service is also available to search images in the database based on R.A. and Decl., or the orbital elements.

    PIXY System 2    

The automated astronomical image examination system developed by Seiichi Yoshida, used in the course of new object survey of the MISAO Project. It is implemented using Java language and it runs both on a Windows PC and a UNIX workstation. Now the version 2 of the PIXY System is being developed.

The PIXY System is a free software. The source files and documents are also available.
