新版的论坛在发布数据的代码方面还是有点BUG，带有格式的数据会发生乱码和错位，以前的旧论坛很少发生这种情况。 北半球不行啊！::070821_15.jpg:: 苏哥在关键的时候 总是比我快~~~~~~~~~~~~~::070821_16.jpg:: 而且数据量大 原帖由 活动星图 于 2008-1-13 00:18 发表 http://www.astronomy.com.cn/bbs/images/common/back.gif
而且数据量大 呵呵 我提供发现细节为主 以后CMCN可能改版做得更好 希望多提意见啊! 好啊我也喜欢看故事 近地点

有17P这个重量级摆着，其他彗星现在看来都像小丑::070821_18.jpg::
哈 17P 现在太弥散了
不过17P一直没有以彗星的传统面貌示人
