Last week North Next week

Best time and the azimuth, altitude (A,h) are at lat. 35 deg in the Southern Hemisphere.

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 kept brightening rapidly and it reached up to 8.0-8.5 mag on Nov. 26 (Michael Jager and Gerald Rhemann). However, it is locating extremely low in the evening, and it will be unobservable soon. It will pass only 0.17 A.U. from the sun in mid January, and reach to 1 mag. But it is not observable at that time. In the Southern Hemisphere, it appears at 3.5-4 mag in late January, then it keeps observable while fading gradually. In the Northern Hemisphere, it will never be observable again. Date(TT) R.A. (2000) Decl.

It became easily visible with naked eyes, and a very long tail of 5 degrees was visible with binoculars. But now it is fading, and it has already faded down to 8.5 mag (Nov. 30, Toni Scarmato). 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. Date(TT) R.A. (2000) Decl.

In October, after it appeared again in the morning sky, it brightened very rapidly from 13 mag up to 10 mag. Now it is 9.1 mag (Nov. 26, Juan Jose Gonzalez). 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. Bright and large, but weakly condensed. It keeps observable in excellent condition in the Northern Hemisphere. It will fade out rapidly after January. Date(TT) R.A. (2000) Decl.

Strongly condensed and easy to see. 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. Date(TT) R.A. (2000) Decl.

CCD observers reported as 14 mag, but it was reported much brighter visually as 11.5 mag (Oct. 14, Juan Jose Gonzalez). It was 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. Date(TT) R.A. (2000) Decl.

When it appeared again in the morning sky, it has showed a cometary activity and it has become much brighter than expected. Now it is also visible visually at 13.7 mag (Oct. 31, Seiichi Yoshida). 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. Date(TT) R.A. (2000) Decl.

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. Its tail became visible again in late October, however, now it is stellar. 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. It may suddenly become active and brighten rapidly someday. But actually, it is getting a bit fainter than this ephemeris recently.

The condition is good in this return. It was expected to reach to 13.5 mag in November. But actually, it is fainter than expected. Now it is 15.4 mag (Nov. 25, Ken-ichi Kadota). Because it is very diffuse, CCD observers report it very faint. However, if the sky condition is excellent, it will be visible visually at 14 mag. It is getting higher gradually after this also in the Northern Hemisphere. By the way, it was reported as 12 mag in mid November, but it seems to be confused by nearby faint galaxies. Date(TT) R.A.

But actually, it is 15.8 mag (Nov. 21, Mitsunori Tsumura), much fainter than expected. It will be observable in an excellent condition in November and December. However, it reached only to 15.5 mag at best in fact. Date(TT) R.A. (2000) Decl.

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 faded rather rapidly in October, and faded down to 11.6 mag on Oct. 31 (Seiichi Yoshida). It looked about to be disrupted on Michael Jager and Gerald Rhemann's image. It got diffuse and faded out rapidly in November. It faded down to 17.0 mag on Nov. 24. It is already invisible visually, and difficult to catch even with CCD. It will return to its original feature, a tiny faint NEO, soon. It keeps locating observable until summer. But in the Northern Hemisphere, it becomes low in the south in 2007. Date(TT) R.A.

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. It was still visible visually at 12.2 mag on Oct. 31 (Seiichi Yoshida). However, it faded out rapidly in November. It faded down to 18.1 mag on Nov. 26. In the Northern Hemisphere, it keeps locating very high in the evening sky for a long time after this. However, it is already fainter than 18 mag. Date(TT) R.A. (2000) Decl.

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 has faded down to 17.4 mag (Nov. 9, Y. Sugiyama). It keeps locating in the evening sky for a while after this. But it will be fainter than 18 mag soon. Date(TT) R.A. (2000) Decl.

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. If it locates within 30 arcmin from the predicted position, it is fainter than 17.5 mag (Nov. 15, Michael Jager). Date(TT) R.A. (2000) Decl.
