* 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. Now the nuclear brightness is 18.5 mag (Oct. 2, Francois Kugel). The coma and tail around the nucleus looks bright, and the total magnitude of the central part may be around 15 mag. Maybe visible visually with a large telescope.

* 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 7.6 mag (Oct. 25, Marco Goiato). It became observable in the evening low sky also in the Northern Hemisphere. 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 is only observable until late October.

* 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. Getting lower in the evening sky. It will be unobservable temporarily in November, 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.

* 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 9.3 mag (Oct. 24, Marco Goiato). In the Northern Hemisphere, it locates extremely low now. Although it will be getting higher slowly after this, it will be fading gradually. However, it keeps observable in the evening sky until it becomes fainter than 18 mag early 2009.

* 85P/Boethin

It is expected to reach up to 7 mag in winter, and will be observable in good condition. However, this comet has not been observed since 1986. It is predicted to be brightening up to around 10 mag, bright enough to be recovered. However, it was not detected, fainter than 20 mag on Sept. 26 (Gustavo Muler), and fainter than 17.2 mag on Oct. 18 (Katsumi Yoshimoto). 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.

* C/2006 W3 ( Christensen )

Brightening very rapidly, faster than expected. It is already so bright as 10.3 mag (Oct. 20, Maik Meyer). 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.

Now it is bright as 10.8 mag (Oct. 23, V.M.Ivanov). It keeps observable in good conditioni as bright as 11 mag from autumn to winter. It keeps observable, visible visually, brighter than 14 mag for a long time until 2009 May.

* 19P/Borrelly

Now it is 10.9 mag (Oct. 9, Juan Jose Gonzalez). 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.

Now it is bright as 11.5 mag (Aug. 4, Marco Goiato). It keeps bright at 12 mag for a long time from 2008 spring to 2009 spring. However, it is not observable in the Northern Hemisphere. 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.

* 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. Now it is so bright as 11.0 mag visually (Sept. 24, Juan Jose Gonzalez). Much brighter than originally predicted, by 3 mag. It locates extremely low in the Northern Hemisphere.

* 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). Now it is not observable. In the Northern Hemisphere, it will appear in the morning sky again at 13 mag at the end of 2008, then it keeps bright and observable for a while.

* 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 bright as 12.1 mag (Oct. 4, 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.

* C/2007 W1 ( Boattini )

It became so bright as 4.7 mag, and so large as 20 arcmin in June (June 12, Marco Goiato). Now it is fading. But it is still visible visually at 12.4 mag (Oct. 4, Seiichi Yoshida). It keeps observable in good condition for a long time after this. Although it is extremely diffuse now, it will be visible visually for some more time in the excellent sky condition.

* 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.

It had been lost for 112 years sincd 1896, but re-discovered by Koichi Itagaki and Hiroshi Kaneda on Sept. 10. It should be bright temporarily in outburst now. However, it still keeps bright as 13.2 mag (Oct. 19, Juan Jose Gonzalez). It keeps locating high in the evening sky for a while after this, but it can fade out rapidly.

Not recovered yet, but it must be brightening very rapidly in the evening sky. It is expected to reach up to 7.5 mag in January. However, it is not observable for about a month around the highlight. In the Northern Hemisphere, it keeps locating low in the evening sky until the highlight. But it turns to appear in the morning sky after February, then it keeps observable in good condition while fading gradually. In the Southern Hemisphere, it locates high except for January.

It had been lost since its discovery in 1892, but finally recovered. It passes extremely near by the earth in October. Now it is bright as 16.0 mag (Oct. 21, Michael Jager). However, because it is a very tiny comet, it will fade out very soon. It will be fainter than 18 mag in late November, and fainter than 20 mag in late Decemeber. In addition, it moves southwards very fast.
