Surprisingly, a great outburst occured on Oct. 24 and now it becomes so bright as 2.5 mag, visible with naked eyes! Almost stellar, so it looks like a nova. It was observed as 14.5 mag in July, then it had been fading down to 17 mag until mid October as predicted. This comet was also in great outburst at the discovery in 1892 and became so bright as 5 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.

It will approach down to 0.4 A.U. to the sun on Oct. 28, and it is expected to reach to 4 mag. Now it is 6.1 mag (Oct. 19, Juan Jose Gonzalez), bright even in the extremely low sky. However, the brightening pace slowed down and it kept 6 mag since Oct. 10. In the Northern Hemisphere, it locates extremely low, slightly over the horizon, in the evening sky until late October. Then it will never be observable again. In the Southern Hemisphere, it will appear in the evening sky in early November, then it keeps observable while fading gradually, although it will not locate very high.

New bright comet. Now it is 10.6 mag (Oct. 14, Mike Linnolt). It must have been locating observable and brightening gradually in the Northern Hemisphere for a while, but it was not discovered until early October. In the Northern Hemisphere, it will be getting lower and lower, then it will be unobservable in early November. In the Southern Hemisphere, it will be unobservable for 1 month after mid November, but it will be observable in good condition at 10 mag from mid December to February. In the Northern Hemisphere, it will appear in the evening sky at 11 mag in March, then it keeps observable while fading gradually until May.

It reached to 7.2 mag on July 14 (Maik Meyer), then it faded down to 9.0 mag on Aug. 13 (Carlos Labordena). It had been unobservable for a while. But in the Southern Hemisphere, it will appear in the morning sky in late October at 13 mag, then it keeps observable while fading gradually. In the Northern Hemisphere, it will appear again at 14 mag in the very low sky at dawn in mid November. But it will be fading while keeping extremely low.

It will reach to 6 mag in January, and will be observable in good condition. Now it is 15.4 mag (Oct. 7, Masayuki Suzuki), but very diffuse. Brightening rapidly, and it will become visible visually soon, although it was not visible visually, fainter than 14.6 mag, on Oct. 5 (Seiichi Yoshida). In the Northern Hemisphere, it keeps observable all night until mid December, then keeps observable until early February, when it fades down to 7.5 mag. In the Southern Hemisphere, it is not observable until late December. But after that, it keeps observable until it fades out.

It was 14.1 mag on Oct. 1 (S. G. McAndrew), 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. In the Northern Hemisphere, it will appear at 13 mag from October to December in a short time, but very low and hard to observe. However, it will be visible visually at 11 mag in the evening sky from March to June in 2008. 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.

It was observed at 16.5-17 mag in last winter. It will be observable in good condition also in next winter. It is expected to reach to 16 mag. However, Mt. Lemmon Survey reported it so faint as 19 mag in September and October. 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.

Peculiar asteroid moving on a cometary orbit. It was asteroidal at 18 mag in late August. It will reach to 15 mag in February and March. In the Northern Hemisphere, it keeps observable until July when it becomes fainter than 18 mag. It may show a cometary activity after this, although the perihelion distance is somewhat large as 1.8 A.U.

It was observed bright as 14-15 mag in 2004 and 2005. Now it is close to the aphelion, but it will be observable at 17.5 mag in good condition in 2007 autumn.

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.
