Great outburst occured on Oct. 24, 2007, and it bacame a naked eye comet of 2 mag. It kept so bright as 5.5 mag still on 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. Now appearing in the morning sky, but still low. It will become observable in good condition in 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 18.6 mag (Sept. 14, Gustavo Muler).

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 14 mag, bright enough to be recovered. However, it was not detected, fainter than 19.5 mag on Aug. 10 (Gustavo Muler), and fainter than 20 mag on Aug. 23 (Francois Kugel). It will brighten very rapidly near by the perihelion. 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.

Now it is 15.1 mag (Aug. 1, John Drummond). It is not observable 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.
