转帖：我发现了一颗非同寻常的SOHO彗星
详情请见下面这个帖子：标题: 我发现了一颗回归的SOHO彗星(C/1999 R1 = C/2003 R5 = C/2007 R?)
http://www.astronomy.com.cn/bbs/thread-78043-1-1.html 这算“找到”而非“发现”吧？方位早就算好了，就看谁第一个看见并报告了。 然而，这颗彗星“应该”是有发现权的；
稍后，专家也会给予编号的。::42:: 赞运气

这两样你都……::42:: 呵呵～～～～::42::
恭喜呀～～～ 祝贺周波
谢谢各位啦!

[ 本帖最后由 周波 于 2007-9-14 13:40 编辑 ] 顶一下,波,同喜中....
谢谢！下面，我再简单地说说它为什么与众不同：
这是我目前已发现的85颗SOHO彗星中最特别的一颗了。不光是因为它是一颗非克族彗星，而是一个目前已发现数量最少的科里奇特（II）族彗星；
不算这次的发现，历史上也只发现过三次这个族的彗星；
现在，又证明其中的1999 R1、2003 R5和这次刚发现的2007 R5，其实是同一颗SOHO彗星。
尽管它可能比不上任何一颗目视彗星或者SWAN彗星，
但它的发现在所有已发现的1350多颗SOHO彗星中，还是比较特别的一颗。
另外，再换一个角度说：
我好象记得从2004年开始SOHO彗星的发现，就基本上不在“IAUC”上作通报了；
这次能在IAUC上通报，本身也就说明了它是一颗非同一般的彗星！

IAUC 8871
K. Battams, Naval Research Laboratory, informs us that B. Zhou
reported his detection of a member of the 'Kracht II comet group'
in SOHO-LASCO C2 data on Sept. 10; the object was immediately
confirmed by R. Kracht as showing 'Kracht-II' group motion.

摘录——
Hi list,
IAUC 8871 and 8872 officially announce and confirm the identity of the SOHO
comet found by Bo Zhou on Sep. 10, 2007, with comets 1999 R1 and 2003 R5, as
predicted by Sebastian F. Hönig in 2005, and published in Astronomy and
Astrophysics <b>445</b>, 759 (2006). The linked orbit by B. G. Marsden,
based on only the C2 observations (with re-measured positions of the 1999,
and 2003 apparitions) indicate a perihelion date of Sep. 11.32, compared to
the prediction by Hönig of Sep. 11.26, which was thus only about 1.5
hours too early! M. Knight (University of Maryland), who has analysed the
brightness behaviour of this comet in all three apparitions remarks that the
lightcurves are more typical for a comet with several brightness peaks. The
evolution at all three apparitions is remarkably similar. It should also be
noted that the comet has not yet been detected in STEREO imagery, which is
typical for comets, where only bright ones are seen while minor planets can
be detected to a much fainter magnitude. The comet will most likely be
numbered 192P and the overall count of SOHO comets will be reduced by one.
Again congratulations to Sebastian!
Cheers, Maik
