Winter Solstice

Tomorrow morning, December 30, 2001, at 5:40 a.m. EST, before dawn, the moon becomes full. As this is the full moon closest to the Winter Solstice, that means that tonight, Dec. 29/30, will be the longest night of the year to be lit by a full moon in North America. In Europe, the moon does not become full until after dawn, 10:40 GMT, and so the night of Dec. 30/31 will be the longest full moon night. No matter the length of the night, the full moon always rises at dusk and sets at dawn. Thus, this night's full moon, often called The Long Night's Moon, will be in the sky longer than any other full moon of the year. (Info thanks to Hester.)
