宇宙给我的新年礼物
除夕在亲戚家吃多了晚上睡不着，找SOHO到年初一的凌晨两点，我在c2的图片里发现一颗非族彗星，这是我的第十七颗SOHO彗星，以及第一颗非族彗星。小家伙运动的很缓慢~~祝贺lz::070821_09.jpg:: 什么东西来的？ LZ大牛能发现非族彗星真是太牛了！
祝贺祝贺！
另外祝新春快乐！ 4# yugang
昨晚发现它真是太意外了~~ Zhijian's non-group comet

If my calculations are correct comet might be visible in early morning LASCO C2
images from 2010 02 13 in the same area with moving left to right/down to up
with mag ~9 (?).
