　　The geminids observation time

For those willing to brave the cold to watch the meteor group of people, the geminids group is a fairly distinctive landscape in in the winter, even on the evening of December 13 more than August Perseid meteor shower.Astronomer David and Stephen said, "if you've never seen the geminids meteors group in the vast arc across road clearly in the night sky, so you can't say you have seen meteor."

Watch the geminids depends on the best time of observation.From darkness came just this period of time until the moon rises, the Gemini alpha star in the east or the northeast horizon, this is a good observation time.

During this time, Earth - grazing meteor may also appeared above the horizon (and sometimes even below the horizon), long long tails to slide horizontally through the atmosphere.So the best viewing time is's midnight, the moon rises on the night this time.The cold winter night, need to wait for the meteor group, need to pay attention to cold warm.
