Although it had been locating low in the morning sky until early October, it turned to the evening sky, and now it is getting higher. It reached to 5.5 mag in early October (Oct. 6, Jose Carvajal). Very strongly condensed and easy to see. It keeps 6-7 mag until the end of October. In the Northern Hemisphere, it keeps observable in the evening sky until early January while fading gradually. In the Southern Hemisphere, it cannot be observable until next April when it becomes fainter than 15 mag.

Now it is 10.7 mag (Oct. 6, Jakub Cerny). It is somewhat fainter than this ephemeris, however, it is well condensed and easy to see. The long dust tail is clearly visible. It keeps 9-10 mag until January, and observable in its best condition. It keeps 14 mag still in 2007 March, so it keeps visible visually for a long time.

New comet discovered visually very near by Saturn. It is very bright, 9.4 mag on Oct. 5 (Juan Jose Gonzalez). But it was fainter than 12 mag in the photo on Sept. 30 (Tetuo Kudo). Probably, it brightened rapidly in early October. It is a short periodic comet with a period of 5.4 years. It may be one of the faint NEOs usually. The comet will be fading gradually after this. But it may fade out rapidly. It keeps locating in the morning sky until winter, then it keeps locating observable until next summer. But in the Northern Hemisphere, it becomes low in the south in 2007.

Although it was reported so faint as 17 mag at the discovery, it was actually much brighter as 14 mag (Aug. 21, Terry Lovejoy). Then it is brightening rather rapidly and it is already so bright as 11.7 mag (Oct. 12, Juan Jose Gonzalez). However, it is very diffuse, locating extremely low in the evening, so it is hard to see. It will pass only 0.17 A.U. from the sun in mid January, and reach to 2.5 mag. But it is not observable at that time. In the Southern Hemisphere, it appears at 5 mag in late January, then it keeps observable while fading gradually. But in the Northern Hemisphere, it is only observable until early November.

Recovered after 117 year blank since 1889. It brightened rapidly in mid July and reached to 8 mag. Then it kept bright at 8 mag with a large diffuse coma until early September. But it has already started fading. Now it is 10.9 mag (Oct. 10, Jakub Cerny). It will fade out rapidly after this. Because it is very diffuse, it can be invisible soon. In the Northern Hemisphere, it keeps locating very high in the evening sky for a long time after this. It moves around the Northern Pole, so it will be observable all night until November, although it becomes low in the morning.

It had not been observed for a long time since June. When it appeared again in the morning sky, it has become much brighter than expected, 12.9 mag (Oct. 8, Y. Sugiyama). It keeps 12 mag until December and it is observable visually in excellent condition. Then it keeps observable until February when it becomes fainter than 18 mag in the Northern Hemisphere.

A small outburst occured in late August, and it was visible visually, bright and strongly condensed, in early September. It is visible at 13.4 mag still now (Sept. 27, Seiichi Yoshida). Another small outburst happened in early October. Since it appeared in the morning sky in early July, it has been bright as 13 mag and visible visually. It is observable in good condition until winter.

It has been lost since its discovery in 1986. The condition is good in this return. In calculation, it was expected to be 14 mag from autumn to winter. But actually, it must be much fainter than expected. Although it has been listed up as an observable target since May, it has not been recovered yet. It was probably in outburst and brightened unexpectedly at the discovery. In the Northern Hemisphere, it keeps observable until it fades out in next spring. When it becomes brightest in October and November, it will move away from the Milky Way. So it will be easier to recover.

It was missed in 1999 due to the bad condition. The condition is good in this return. It will reach to 13.5 mag in November. Although it is too low in the Northern Hemisphere now, it locates high in the Southern Hemisphere. It must be already bright as 14 mag, but it has not been recovered yet. In the Northern Hemisphere, it will be getting higher gradually after mid October.

Now it is 14.3 mag and almost asteroidal (Sept. 20, Edwin van Dijk). Although the slight cometary activity was detected in late July, its faint tail became too hard to detect now. In the Northern Hemisphere, it keeps good condition after this. It keeps locating high until next spring. If it keeps asteroidal after this, it will be 14 mag at best. However, it may suddenly become active and brighten rapidly someday.

It was in major outburst unexpectedly and reached to 10.5 mag in its last appearance in 1999. It was already recovered in 2005 October. But it has not been observed for 1 year since that. So the current brightness is quite uncertain. It has already appeared in the morning sky. It is expected to be 15.5 mag, but actually, it can be much fainter than this ephemeris. It will fade out gradually after this.

But in 2007 and 2008, it is expected to be bright as 14.5-15 mag. It will locate high at that time, so it may be visible visually.

It reached to 6 mag at best in early May at the remarkable approach to the earth, when it became double naked eye comets with the component B around the zenith. Now it is going away from the earth and fading. It has already faded down to 13.9 mag (Sept. 27, Seiichi Yoshida). It will be too faint to see visually soon. However, it can be much brighter than this ephemeris. The component B has faded out rapidly since June, and already so faint, fainter than 17 mag.
