Predicted Maximum: December 13, ~23:00 UT (=Dec. 13, 3pm PST; =Dec. 13, 6:00pm EST)

Moon: Full (major interference)

WHEN TO WATCH: The Geminids have a fairly broad maximum, so viewing should be productive during the morning hours of Saturday, December 13 and again for the entire night of December 13/14 (late Saturday evening into Sunday morning). The Moon will be a huge fly in the ointment this year; clean, clear air will help a bit. The Geminids tend to be brighter just after maximum activity, pointing to late Saturday evening and early Sunday morning as the best bet.

The radiant is highest in the sky at around 2am. The Geminids can produce observed rates of up to 100/hour at maximum, but this year the Moon will allow us to see only a bare fraction of the show (depend on local light pollution and sky conditions). However, meteor activity is visible on any clear night.

Geminids are medium-speed meteors. Most of them don't leave glowing trains, but the brighter ones are often colored (yellow, green and blue are most common).
