Great outburst occured on Oct. 24, and it bacame a naked eye comet of 2 mag. It still keeps so bright as 3.8 mag on Jan. 25 (Toni Scarmato). 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.

It passed near by Earth in early January, and it became a bright large object at 5.4 mag (Jan. 3, Seiichi Yoshida). It was visible with naked eyes. However, it has already faded down to 6.4 mag (Jan. 25, Marco Goiato). Now the comet is moving southwards very rapidly. In the Northern Hemisphere, it keeps observable until early February, when it fades down to 7.5 mag. In the Southern Hemisphere, it keeps observable until it fades out.

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.

New bright comet. It is already visible visually at 14.0 mag (Jan. 12, Alan Hale). It is expected to be 7 mag in September. But it keeps moving in the southern sky, so it is difficult to see in the Northern Hemisphere. It will be locating in the very low sky at about 10 degree high until mid March, then it becomes unobservable in the Northern Hemisphere. It will appear in the evening sky at 7 mag in late September, but 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 keeps observable until late October after this.

The return of a comet discovered in 2003 by SOHO spacecraft. It can be a short periodic comet with a period of about 4 years. If so, it is expected to return in 2008 spring. If it passes the perihelion in spring, it will be visible at 12-15 mag in the evening sky. But the period is quite uncertain with an error of several months. So we have to wait until it is re-discovered by chance.

But it will be brightest after the perihelion passage. It will be visible at 14 mag until February. But the altitude will be around 30 deg. Then it is observable until April when it becomes too low at 17 mag.

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.

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. No observations have been reported recently, and the current brightness is uncertain. 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.

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.
