this is the our photo of the comet done to the 19:44 TU from Talmassons, with
crossing of
clouds in front of her... is impressive!
observed with the binoculars it seems me equal to the star delta Per, with a
reddish
color.
哈哈！我这儿，现在是晴天！！！

This ia an AstroAlert from Sky & Telescope.
October 24, 2007
A distant comet that was as faint as magnitude 18 on October 20th has suddenly brightened by a millionfold, altering the naked-eye appearance of the constellation Perseus.

今晚只要是晴天，大家就应该能看到它了。哈哈！::42:: ！没尾巴的，有点像超行星爆发::070821_05.jpg:: 波啊
哈哈
记得我前面用17P做例子吗？::42::
没想到竟然变成现实了 增亮得这么快！？。。。。。。。。。 29楼那张真诡异啊::0020:: 原帖由 suhuasky 于 2007-10-25 10:05 AM 发表 http://www.astronomy.com.cn/bbs/images/common/back.gif
从彗星的距离看，应该是分裂或被撞，而且亮度爆发不会持续很久
是
貌似彗星在小行星主带？好惨。。。 引用: antares21 在文中说道:
29楼那张真诡异啊
孟奂也拍了，是用国台兴隆站的80cm，拍得像个大饼，没有尾巴和彗发。。。 原帖由 北斗流星月 于 2007-10-25 12:42 发表 http://www.astronomy.com.cn/bbs/images/common/back.gif
再坚持3天!
为什么再等三天啊？天气预报显示今晚晴间多云，明后天都多云啊。
PS：这颗彗星叫福尔摩斯啊！有意思。。。 READY ,GO,IT is amazing！晚上准备行动，但愿污染少点！ Comet 17P Holmes, a very obscure and dim object to say the least only 30 hours
ago, is
blazing away at a brightness increase rarely seen before in such a short period
of time,
rising more than 15-16 magnitudes since October 23. Now at brightness 2.0 (ASO,
Oct. 25
UT, 04:10) and perhaps still brightening, this comet must be watched
continuously for
the next several weeks.
It appears as you seen in the first light photo from ASO; this is an RGB color
image
from an ST 401-ME camera, 12 second images in each color and combined. No post
processing, just a raw image, showing the brilliant round yellow-green huge
(nearly 3
arc minutes across) coma. The very high contrast negative imaging reveals a
possible
dust tail coming nearly due north (down) from the comet as well as one streaming
from
the south side of the coma. The image was taken with a 0.4m SCT at f/3 at the
observatory (Harvard MPC H45) at Petit Jean Mountain in Arkansas.
This unusual "round comet" to be so bright without a tail or irregularity is
something
very extraordinary. The comet can easily be seen with the naked eye, but even
binoculars and telescopes give the impression that the viewer is peering at a
very
bright star.
The field of view in both ASO images is 12 arc ' by 7' with SOUTH up.
For those with no image attached, please visit the report with both color and
high
contrast negative (showing possible dispersion from the coma), at the Arkansas
Sky
Observatory (ASO) website under the "ASO News Links" on the home page at:
