Surprisingly, a great outburst occured on Oct. 24, and it bacame a naked eye comet of 2 mag. It still keeps so bright as 3.1 mag on Nov. 21. It was completely stellar just after the outburst, however, then a round disk like coma is getting larger gradually. The coma has bcome larger than Moon, and the comet has bacome very diffuse. So it looks like a huge faint 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 further brightness is uncertain. But the comet will be observable in excellent condition for a while after this.

Already unobservable in the Northern Hemisphere, but it is appearing 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 has already faded down to 8.4 mag (Nov. 20, 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.

Now it is bright as 13.0 mag and visible visually (Nov. 15, Alan Hale), brightening well as expected. It will reach to 11 mag in 2008 spring. It will keep bright for a long time, however, it keeps moving in the southern sky for a while after this.

It passed near by the earth in early April, and reached to 8.7 mag (Apr. 10, Werner hasubick). Then it faded down to 11.8 mag on May 26 (Seiichi Yoshida), and became too low to observe in the evening. It has already faded down to 17.4 mag (Oct. 5, Yasukazu Ikari).

It reached to 13.5 mag and became visible visually in 2005 and 2006. Now it has gone far away. But it is still bright as 16.4 mag (Oct. 6, Ken-ichi Kadota), brighter than this ephemeris. It locates in the good position in this winter, so it will be observable at 17 mag for some more time.

It was observed at 16.5-17 mag in last winter. It will be observable in good condition also in this winter. It should be 16 mag by calculation. However, it was so faint as 18.5 mag in autumn, much fainter than expected. It was observed so faint around the perihelion passage in the previous apparition at the discovery. So maybe it suddenly faded out before the perihelion passage again.
