The Geminids (GEM) peak on the night of December 13/14. Rates will
rise steadily this week as we approach the maximum and the moon wanes.
The current radiant is located in northern Gemini, five degrees west
of the second magnitude star Castor (Alpha Geminorum). These meteors are
best seen near 0200 local standard time when the radiant lies highest
above the horizon. This shower is best suited for the Northern
Hemisphere but some activity can be seen south of the equator when | g****e

已经有了, ZHR=120,注意安全,注意保暖.
imo的主页有辐射点的位置,不过看的时候不要看辐射点,那样看到的太少,
应该看离辐射点30-40度左右距离的地方, 然后就看运气了, 人多看比较好,
一是安全热闹,二是覆盖更多天区.
我明天会出去找个黑地方看看,不过问题是明天我这里多云:( | g****e
