Great outburst occured on Oct. 24, and it bacame a naked eye comet of 2 mag. It still keeps so bright as 3.3 mag on Jan. 4 (Seiichi Yoshida). It did not fade at all since late November. It was completely stellar just after the outburst, however, then a round disk like coma is getting larger gradually. The coma diameter has increased up to about 90 arcmin, and the comet has bacome very diffuse. So it looks like a huge nebula now. This comet was also in great outburst at the discovery in 1892 and became so bright as 4 mag. At that time, the comet faded after the first outburst, but soon brightened again in the second outburst. The comet will be observable in excellent condition for a while after this. It will be easily visible with naked eyes for a while in the dark sky.

Now it is bright as 12.6 mag and visible visually (Dec. 30, Marco Goiato), brightening well as expected. It will reach to 11 mag in spring. It will keep bright for a long time, however, it keeps moving in the southern sky for a while after this. In the Northern Hemisphere, it keeps extremely low and hard to observe for a while. However, it will be getting higher after March, and will be visible visually at 11 mag in the evening sky until June. Then it becomes unobservable again. But 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.

Already unobservable in the Northern Hemisphere, but it is observable in the evening low sky in the Southern Hemisphere. It approached down to 0.4 A.U. to the sun on Oct. 28, and it reached to 5.3 mag (Oct. 25, Juan Jose Gonzalez). Now it is fading. It had already faded down to 10.1 mag on Dec. 1 (Marco Goiato). The brightening became very slow just before the perihelion passage, but it started fading rapidly after the perihelion passage. It will never be observable again in the Northern Hemisphere. But in the Southern Hemisphere, it keeps observable while fading gradually, although it will not locate very high.

It passed very near by the Earth in early December, and became bright as 12.6 mag (Dec. 5, Juan Jose Gonzalez). The very fast motion was easily observed in the excellent condition. However, it became unobservable in mid December. It will be extremely low in the evening at 16-17 mag in February. But actually, it will never be observable again in this apparition.

Now it is brightening up to 16.7 mag (Dec. 19, P. C. Sherrod). It will pass 0.85 A.U. from the sun in late June in 2008, and it is expected to reach to 6 mag. In the Northern Hemipshere, it keeps observable in good condition for a long time after this, while the comet is brightening gradually. The comet will be 14 mag in February and become visible visually. Then it is observable until around May 25, when the comet will be 7.5 mag. It will be unobservable for one and a half month around the perihelion passage. But it will appear in the morning sky again at 7 mag in early July, then it keeps observable after that while the comet is fading gradually. In the Southern Hemipsphere, it keeps observable all the period until the comet fades out, although it will be low in mid June.

It was observed bright at 16.5-17 mag from late 2006 to early 2007. However, it is fading after that, although it is getting closer to the sun. Now it is observable in good condition, but very faint at 18.4 mag (Nov. 21, Ken-ichi Kadota). This comet was observed so faint around the perihelion passage in the previous apparition at the discovery. So probably, it faded out before the perihelion passage again.
