December's full Moon, which sails across the south tonight, is known as the Long Night Moon. It is in view for more hours than any other full Moon -- a good 13 or 14 hours for most of the country, with up to about 16 hours of moonlight from far-northern latitudes.

This full Moon is the biggest full Moon of the year. It is a "perigee Moon," as much as 14% bigger and 30% brighter than lesser full Moons we've seen earlier in 2008.
