亮度大約多少等????
上边星历表不告诉你了…… 观测还需要一定的经验才行 直接GOTO过去，再对照星图，不难吧

最快时的速度是多久一度？
从星历表中大约就可以看出来了，大约一小时一度。::31::
兔子早啊
我非得导进SKY MAP里才能知道…… 你把轨道根根数和星历表导进去不行吗？？ 哈哈，貌似这颗是我确认地说…… 找一下图…… 图片找不到了，只有确认时的观测数据：K06V02VC2006 11 12.56803 03 01 15.60 +57 37 03.0 18.8 V EV047D35

有条件的同好可以考虑观测下，详细的观测记录可以参加本月的观测记录比赛::32::
我拿上面这个参加可以不？::24:: ::37:: 原帖由 新疆高兴 于 2007-2-4 22:22 发表
极度关注，请苏提供更详细的星历表，有没有SKYMAP文件？
public能搞到的最详细的星历表 for C42
可惜运动太快了，不然可以搞photometry什么的……
