Last week South Next week

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

85P/Boethin It was expected to reach up to 7 mag and to be observable in good condition in winter. However, this comet has not been observed since 1986. It was not detected, fainter than 17.2 mag on Oct. 18 (Katsumi Yoshimoto), and fainter than 20 mag on Nov. 3 (Gustavo Muler). It seems much fainter than expected. The condition of this apparition is good. It keeps observable for a long time until 2009 early summer both in the Northern Hemisphere and Southern Hemisphere. Date(TT) R.A. (2000) Decl.

It is expected to reach to 4 mag in 2009 February. It is not observable now. But it will appear in the morning sky again at 7 mag in late December. Then it keeps observable in the excellent condition long time around the highlight until spring. Date(TT) R.A. (2000) Decl.

Now it is still bright as 8.7 mag (Nov. 22, Seiichi Yoshida). 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 will never be observable again. Date(TT) R.A.

It is already so bright as 9.7 mag (Nov. 29, Maik Meyer). Strongly condensed and easy to see. It is expected to reach to 8 mag in 2009 summer. Because it moves in the northern sky, it keeps observable until it becomes brightest in the Northern Hemisphere. Date(TT) R.A. (2000) Decl.

It keeps bright at 12 mag for a long time until 2009 spring. However, it is not observable in the Northern Hemisphere now. It will appear in the northern sky again in 2009 autumn, but it will be fainter than 15 mag and will keep locating very low after that. In the Southern Hemisphere, it keeps observable for a long time until it fades out, although it becomes low in autumn. Date(TT) R.A. (2000) Decl.

Now it is fading slowly. It has faded down to 12.0 mag on July 21 (Alexandre Amorim). Now it is appearing in the morning sky after a long blank. It keeps bright as 12-14 mag for a long time after this until 2009 summer. Date(TT) R.A. (2000) Decl.

Now it is fading. It has already faded down to 12.5 mag (Nov. 22, Seiichi Yoshida). It keeps observable and fading in the morning sky after this. It keeps brighter than 14 mag and visible visually until the end of 2008. In the Southern Hemisphere, it keeps extremely low, or under the horizon, so it will not be observable. Date(TT) R.A.

It must be brightening very rapidly in the evening sky. However, it was not detected, fainter than 18 mag, on Nov. 22 (Maik Meyer). It is expected to reach up to 7.5 mag in January, but actually it may be much fainter than expected. It is not observable for about a month around the highlight. In the Northern Hemisphere, it keeps locating low in the evening sky until the highlight. But it turns to appear in the morning sky after February, then it keeps observable in good condition while fading gradually. In the Southern Hemisphere, it locates high except for January.

It is extremely low in the Northern Hemisphere now, but observable in good condition in the Southern Hemisphere. It is expected to brighten up to 10 mag from late 2009 to early 2010. Because the comet moves in the southern sky for a long time, it keeps impossible or very hard to observe in the Northern Hemisphere until 2009 September. But after 2009 October, it is observable at 10 mag for a while in good condition. In the Southern Hemisphere, it keeps observable for a long time while brightening until 2009 June when it brightens to 11 mag. But it becomes unobservable around and after the brightest time.

Now it is fading, but still visible visually at 14.1 mag (Nov. 22, Seiichi Yoshida). In the Northern Hemisphere, it keeps observable until 2009 spring when the comet becomes faint. It will move near by the Northern Pole from summer to autumn, and will be observable all night. It will be visible visually for some more time. In the Southern Hemisphere, it will never be observable again. Date(TT) R.A. (2000) Decl.
