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

来自主题: WashingtonDC版 - 今天晚上几点能看到流星雨?
You can see the Geminids meteor shower after sunset if the observation
condition is good. The IMO (International Meteor Organization) calendar
claims the peak is somewhere in the range of Dec 13 2am to 11pm (that's late
tonight to earlier tomorrow night).

来自主题: WashingtonDC版 - 觀雙子座流星雨 明黎明前最佳
今年的雙子座(Geminid)流星雨預計在13日凌晨2時達到最高峰,48小時的最佳觀賞時間
將持續到14日黎明前。
雖然這場雙子座流星雨會因滿月的光芒而略顯模糊,但天文學家表示,雙子座流星
皎潔明亮,在月色中也不遜色。因此在寒風中等待的看客還是能看到不少流星畫過天空。
流星的數量將隨著夜的加深而增多,午夜後漸入佳境。全球範圍內的觀星者可在當
地時間凌晨2時觀賞流星雨,不僅正值最高峰,月亮也開始落下。
雙子座流星雨雖以雙子星座命名,但其流星並不來自雙子星座的星群,到現在它的
來歷仍是個謎。不過這是今年最好的一場流星雨之一,月落後每小時能看到50顆流星。

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:(

Explanation: Northern Lights, or aurora borealis, haunted skies over the
island of Kvaløya, near Tromsø Norway on December 13. This 30
second long exposure records their shimmering glow gently lighting the
wintery coastal scene. A study in contrasts, it also captures the sudden
flash of a fireball meteor from December's excellent Geminid meteor shower.

Explanation: Monstrously bright, this fireball meteor lit up the Mojave
Desert sky Monday morning, part of this year's impressive Geminid meteor
shower. Seen toward the southwest over rock formations near Victorville,
California, a more familiar celestial background was momentarily washed out
by the meteor's flash. The background includes bright star Sirius at the
left, and Aldebaran and the Pleaides star cluster at the right side of the
