December's Cold Moon—the last full moon of the year—will appear in the sky overnight and coincide with a rare lunar event in which observers can see it rise and set at its most extreme points on the horizon.

Get ready for the final full moon of 2024: the Cold Moon. Skywatchers who want to see it at its fullest should be prepared to head out this weekend — the December full moon will reach peak illumination at 4:02 a.

It’s also the last full moon before the Winter Solstice, which falls on Dec. 21. Other names for this month’s full moon: the Frost Moon, the Oak Moon, the Winter Moon and the Moon Before Yule. It’s also called the Long Night Moon because it falls near the solstice, which is typically known as the longest night of the year.
