Geminid meteor shower peaks tonight (no clouds, no moon!)

The Geminid meteor shower is an anomaly, because it's not caused by Earth hitting debris in the tail of a comet, as are most such showers. These come from an asteroid, for reasons not entirely understood. Phil Plat of Bad Astronomy explains here.

As always the best meteor viewing will come after midnight, because of the pattern of the Earth's spin into the debris. It should be clear tonight and the moon is new (i.e., dark), so it might be worth getting out of bed and peering skyward.
