* C/2006 M4 ( SWAN )

After it kept 5.5-6.0 mag from early October to mid October, it suddenly brightened in outburst on Oct. 24, and reached up to 4.2 mag on Oct. 25 (Maik Meyer). It became easily visible with naked eyes, and a very long tail of 5 degrees was visible with binoculars. However, it has already started fading. Now it is 5.2 mag (Oct. 28, Adam Hurcewicz). In the Northern Hemisphere, it keeps observable in the evening sky until early January while fading gradually after this. In the Southern Hemisphere, it cannot be observable until next April when it becomes fainter than 15 mag.

Now it reached to the maximum brightness at 9.6 mag (Oct. 19, Maciej Reszelski). Strongly condensed and easy to see. The long dust tail is clearly visible. It keeps 9-10 mag until December, and observable in its best condition. It keeps observable after that until May when it fades down to 16 mag. It will be visible visually for a long time until around March.

* C/2006 L1 ( Garradd )

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 brightened rapidly after that, and now it reached up to 9.8 mag (Oct. 27, Juan Jose Gonzalez). It keeps brightening even after the perihelion passage on Oct. 17, so the current situation is somewhat irregular. It will be at opposition in December and it is coming closer to the earth. So it will keep visible visually at 9-10 mag for a while until December. It keeps observable in excellent condition in the Northern Hemisphere. It will fade out rapidly after January.

* C/2006 P1 ( McNaught )

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 mag (Oct. 15, Michael Jager and Gerald Rhemann). 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.

* P/2006 T1 ( Levy )

New comet discovered visually very near by Saturn. It was 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. It is fading rather rapidly. Now it faded down to 11.3 mag (Oct. 23, Tsutomu Seki). It will be too faint to see visually in December. 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.

* 177P/2006 M3 ( Barnard 2 )

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 11.0 mag (Oct. 19, Maciej Reszelski). It is not fading so rapidly still now, and now it is brighter than this ephemeris. However, it may fade out rapidly afteer this and may be too faint to observe soon, because it is very diffuse. 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.

* C/2006 L2 ( McNaught )

Because it has been locating low in the evening sky, a few observations have been reported. CCD observers reported as 14 mag, but it was reported much brighter visually as 11.5 mag (Oct. 14, Juan Jose Gonzalez). It becomes too low in the evening to observe in October and November. But it will be getting higher in the morning sky after December. Then it keeps 13 mag until March and visible visually for a long time.

* 29P/Schwassmann-Wachmann 1

Another outburst occured in mid October, and now it becomes very bright as 11.5 mag (Oct. 16, Maciej Reszelski). In this year, it has been bright as 12-13 mag and visible visually since it appeared in the morning sky in early July. It keeps observable in good condition until March.

* D/1986 W1 ( Lovas 2 )

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. It is moving away from the Milky Way, so it will be easier to recover.

* C/2005 YW ( LINEAR )

It had been unobservble for a long time. When it appeared again in the morning sky, it has showed a cometary activity and it has become much brighter than expected, as 14.3 mag (Oct. 15, Ken-ichi Kadota). It may be visible visually at 13 mag. It keeps 13-14 mag until March. It is observable in good condition in the Southern Hemisphere. However, in the Northern Hemisphere, it rises only up to 20 degree in November, then it moves southwards and is only observable until December.

* P/2006 HR30 ( Siding Spring )

Now it is 14.9 mag (Oct. 16, Katsumi Yoshimoto). Almost asteroidal. It did not brighten at all since early September. Although the slight cometary activity was detected in late July, it became completely stellar soon. However, its tail became visible again in late October. 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.

* C/2003 WT42 ( LINEAR )

It has been visible at 13.5 mag for a long time since last autumn until spring. Although it had been unobservable for a while, now it is appearing in the morning sky again. It keeps 14 mag and observable in excellent condition until April. Although it is fainter than last year by 1 mag, it will be visible visually at 14 mag.

It brightened up to 16.7 mag on Sept. 12 (B. Brinkmann). However, it did not brighten furthermore after that, 17.2 mag on Oct. 7 (Ken-ichi Kadota). In its last apparition, it became brightest about 4 months after the perihelion passage. In this apparition, it was expected to reach up to 15.5 mag and to be observable in good condition from November to January. However, maybe it has already started fading.

It is outside of Jupiter's orbit, so it keeps observable for a long time. Now it is 15.6 mag (Sept. 1, Y. Sugiyama). In 2006, it is still faint and locating somewhat low. 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 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.

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. Recently it is fading more slowly than expected. It was visible visually at 13.9 mag still in late September (Sept. 27, Seiichi Yoshida). Now it is still bright as 15.3 mag (Oct. 16, Katsumi Yoshimoto), brighter than this ephemeris. It keeps observable in the evening sky for a while after this.
