貌似刚才确认了一颗新彗星

嘿嘿嘿，这个不叫差了不少吧。随着后续观测的进一步深入，轨道肯定还会变动的。你的计算还是比较准确的。

转IAUC 8806原文，看来这位Daniel写这个也是…… 呵呵。

     An apparent asteroidal object discovered by the Catalina Sky
Survey (discovery observation tabulated below), and posted on the
Minor Planet Center's 'NEOCP' webpage, has been reported by other
observers to show cometary appearance.  CCD images taken by H.-C.
Lin, C.-S. Lin, and Q.-z. Ye (Lulin Observatory 0.41-m f/8.8
Ritchey-Chretien telescope) on Feb. 10.55 UT show a small 3" coma
with an apparent tail around 5"-6" long in p.a. 70 deg.  G. Sostero
and E. Guido (Remanzacco, Italy, 0.45-m f/4.4 reflector) report
that a co-addition of ten unfiltered 180-s CCD exposures on Feb.
11.8 reveals the possible presence of a broad and faint tail almost
12" toward p.a. 340 deg.  D. T. Durig and W. R. O'Farrell (Sewanee,
TN, 0.30-m f/4 Schmidt-Cassegrain telescope) write that their CCD
images from Feb. 12.09-12.16 show a possible coma of diameter 1".5-
3", asymmetric to the north, with a possible tail 7"-9" long in
p.a. 255 deg.

很奇怪彗尾长度和方向都不一致。

还是发全文好了。

appear on MPEC 2007-C54.

别发全文，发译文……

这个英文很浅显，大概不用翻译了。

如果没学过E文呢？

没学过英文的，对本贴大概兴趣也不大吧……

别一棍子打死……
喜欢彗星和喜欢英语有关系吗？

1.不喜欢本贴不代表不喜欢彗星
2.不熟悉英语不代表不喜欢英语


本贴讲的彗星算小家伙... 所以我想吸引程度不太广泛...

你进得了IAUC？？

YTHT！哼唧

想上IAUC有一条近路：找SOHO。
所以，我们这里应该是苏华上的最多了，全国最多的应该也是他

好...........................

这是什么跟什么啊，小龙在忽悠吧
Archimedes应该问的你能不花钱看IAUC内容吗
偷换概念

噢，我还以为文韬说星图进不了IAUC呢。
鹿林有订阅IAUC，有必要的话可以请他们转一份。
不过IAUC的话，……其实…… 期望不要太高
