Science / Medicine : Once in Blue Moon, and It Is Tonight
There will be a full moon tonight, the second full moon of December, which makes tonight’s full moon a blue moon.
The moon itself won’t be blue, however. The phrase refers to the second full moon in one calendar month. The origin of the label “blue moon†seems to be lost in time.
A blue moon occurs only once every several years, giving rise to the expression “once in a blue moon.†The last was in May, 1988, and the next will occur in August, 1993.
A New Year’s Eve blue moon is rarer still. The last time this happened was in 1971 and the next blue moon on New Year’s Eve in the Pacific time zone won’t happen again until 2009, according to the Griffith Observatory.
The Griffith Observatory’s Sky Report can provide additional information about these celestial events. Call (213) 663-8171.
