Geminid Meteor Shower, December 14, 2021.
2021年12月14日, 双子座流星雨。(P) (V)


The weather was good on peak night this year. A minor inconvenience was I had to avoid the full moon which didn't set until 3 am. There were many more bright meteors that traveled long and far than what I saw last year which was off peak. In fact minutes after I pulled onto I66 one burst out right above my windshield and traveled in the same direction I was going for what felt like two full seconds before burning out. On the other hand, while I didn't feel I observed a lot more meteors than last year, that's what my cameras captured.

There was a stark contrast in the number of satellites and planes crashing the show between looking north (fewer) and south (a lot more). A meteor burns out so fast it will almost never get captured by more than one of these relatively long exposures and will show as a quick flash in the time-lapse videos. A satellite or plane remains visible significantly longer and its trajectory can be clearly seen, on the other hand.


今年峰值夜的天气不错,就是满月凌晨3点才落理想的拍摄时间有限。看到了很多又亮又长的流星,其中一颗就在刚出发上高速不久,和我同一个方向飞行了得有两秒钟才熄灭。在那儿的时候感觉看到的流星总数没比去年多多少,整理照片才发现拍到的要多好多。

两个相机一个朝北一个朝南,南方天空中飞过的卫星和飞机数量远超北方。流星的燃烧时间一般很短暂,在缩时摄影中也就是一闪而过。相反的,卫星和飞机体现在缩时摄影中的时间要长很多,飞行轨迹也明显的多。
