Blue Moon On New Year's Eve Tweet

Believe it or not, tonight's full Moon is a "Blue Moon." It's the second full Moon this month and the first Blue Moon to fall on New Year's Eve in nearly 20 years. Sounds like a rare excuse for a party...

There's more. In Europe, Africa and Asia, the Blue Moon will dip into Earth's shadow for a partial lunar eclipse. At maximum eclipse, around 19:24 Universal Time, approximately 8% of the Moon will be darkly shadowed

Blue Moons are rare (once every 2.5 years). Blue Moons on New Year's Eve are rarer still (once every 19 years). How rare is a lunar eclipse of a Blue Moon on New Year's Eve?

A search of NASA's Five Millennium Catalogue of Lunar Eclipses provides an approximate answer. In the next 1000 years, Blue Moons on New Year's Eve will be eclipsed only 11 times (once every 91 years). A year of special note is 2848 when there will be two lunar eclipses in December--on Dec. 1st and Dec. 31st. Such a double-Blue Moon-lunar eclipse ending on New Year's Eve appears to be a millennium-level event. That's rare.
