Rare Full Moon on Christmas Day
Not since 1977 has a full moon dawned in the skies on Christmas. But this year, a bright full moon will be an added gift for the holidays.
December’s full moon, the last of the year, is called the Full Cold Moon because it occurs during the beginning of winter. The moon’s peak this year will occur at 6:11 a.m. EST.
This rare event won't happen again until 2034. That’s a long time to wait, so make sure to look up to the skies on Christmas Day."
