* 17P/Holmes

Great outburst occured in 2007 October, and it bacame a naked eye comet of 2 mag. It kept so bright as 5.5 mag still in 2008 spring (Apr. 30, Carlos Labordena), but it was extremely faint and difficult to see. The size was so large, the diameter was larger than 60 arcmin. It will become observable in good condition in this autumn again. The extremely faint large diffuse object may be detected with a best sky condition, around 5-6 mag with a diameter of 1 or 2 degrees. Current brightness of the central core is 17.8 mag (Oct. 31, Ken-ichi Kadota), much brighter than pre-outburst brightness still now.

* C/2008 A1 ( McNaught )

It reached to 6.3 mag in September in the southern sky (Sept. 4, Marco Goiato). Now it is still bright as 7.7 mag (Nov. 8, Juan Jose Gonzalez). It keeps locating in the evening low sky until the end of 2008 when it fades out down to 10 mag. Then it turns to appear in the morning sky, and it keeps observable in the northern sky after that while fading gradually. In the Southern Hemisphere, it will never be observable again.

* C/2007 N3 ( Lulin )

Now it is 8.5 mag (Oct. 25, Marco Goiato). It is expected to reach to 4 mag in 2009 February. It is not observable now. But it will appear in the morning sky again at 7 mag in late December. Then it keeps observable in the excellent condition long time around the highlight until spring.

* 85P/Boethin

It was expected to reach up to 7 mag and to be observable in good condition in winter. However, this comet has not been observed since 1986. It is predicted to be brightening up to around 9 mag, bright enough to be recovered. However, it was not detected, fainter than 17.2 mag on Oct. 18 (Katsumi Yoshimoto), and fainter than 20 mag on Nov. 3 (Gustavo Muler). It seems much fainter than expected. The condition of this apparition is good. It keeps observable for a long time until 2009 early summer both in the Northern Hemisphere and Southern Hemisphere.

* 6P/d'Arrest

It reached up to 8.5 mag in September (Sept. 24, Juan Jose Gonzalez). Diffuse object expanding a large coma. It is still bright as 9.2 mag (Nov. 4, Marco Goiato). In the Northern Hemisphere, it locates extremely low now. Although it will be getting higher slowly after this, it will be fading rapidly. However, it keeps observable in the evening sky until it becomes fainter than 18 mag early 2009.

* C/2006 W3 ( Christensen )

Brightening very rapidly, faster than expected. It is already so bright as 10.1 mag (Nov. 6, Juan Jose Gonzalez). Strongly condensed and easy to see. It is expected to reach to 8 mag in 2009 summer. Because it moves in the northern sky, it keeps observable until it becomes brightest in the Northern Hemisphere.

* C/2006 OF2 ( Broughton )

Now it is bright as 10.4 mag (Nov. 6, Juan Jose Gonzalez). It keeps observable in good conditioni as bright as 11 mag until January. Then, it keeps observable, visible visually, brighter than 14 mag for a long time until 2009 May.

* C/2007 G1 ( LINEAR )

It brightened up to 11.5 mag in summer (Aug. 4, Marco Goiato). It keeps bright at 12 mag for a long time until 2009 spring. However, it is not observable in the Northern Hemisphere now. It will appear in the northern sky again in 2009 autumn, but it will be fainter than 15 mag and will keep locating very low after that. In the Southern Hemisphere, it keeps observable for a long time until it fades out, although it becomes low in autumn.

* 19P/Borrelly

It reached up to 9.6 mag in summer (Aug. 2, Juan Jose Gonzalez). Now it is fading. It has already faded down to 12.0 mag (Nov. 1, Seiichi Yoshida). It keeps observable and fading in the morning sky after this. It keeps brighter than 14 mag and visible visually until the end of 2008. In the Southern Hemisphere, it keeps extremely low, or under the horizon, so it will not be observable.

* C/2006 Q1 ( McNaught )

It reached to 10.9 mag in May (May 11, Marco Goiato). Now it is fading slowly. It has faded down to 12.0 mag on July 21 (Alexandre Amorim). It is not observable now. But it will appear in the morning sky soon. Then t keeps bright and observable for a while.

* C/2007 Q3 ( Siding Spring )

Already bright as 13.5 mag, and visible visually (Oct. 7, Alan Hale). It is extremely low in the Northern Hemisphere now, but observable in good condition in the Southern Hemisphere. It is expected to brighten up to 10 mag from late 2009 to early 2010. Because the comet moves in the southern sky for a long time, it keeps impossible or very hard to observe in the Northern Hemisphere until 2009 September. But after 2009 October, it is observable at 10 mag for a while in good condition. In the Southern Hemisphere, it keeps observable for a long time while brightening until 2009 June when it brightens to 11 mag. But it becomes unobservable around and after the brightest time.

* 7P/Pons-Winnecke

An outburst occured in late May and it brightened up to 14.6 mag (May 23, Gustavo Muler), but it faded down to the original brightness in late May. Then it had been reported so faint as 17 mag by CCD observations. However, it suddenly became so bright and visible visually after late August, and it reached up to 11.0 mag visually in September (Sept. 24, Juan Jose Gonzalez). However, it is fading now. It locates extremely low in the Northern Hemisphere.

* C/2008 J1 ( Boattini )

Diffuse comet, but it brightened up to 9.8 mag on July 7 (Juan Jose Gonzalez). Now it is fading, but still visible visually at 13.8 mag (Nov. 1, Seiichi Yoshida). In the Northern Hemisphere, it keeps observable until 2009 spring when the comet becomes faint. It will move near by the Northern Pole from summer to autumn, and will be observable all night. It will be visible visually for some more time. In the Southern Hemisphere, it will never be observable again.

Now it is 16.1 mag (Nov. 1, Ken-ichi Kadota). Brightening rapidly. It will reach up to 14 mag from December to February, and will be observable in good condition. It will be visible visually. Then it keeps observable in good condition for a long time until next spring. It was origibally expected to reach up to 10 mag in winter based on the brightness at the discovery. But actually, it is much fainter than that prediction by 4 mag.
