"BLUE MOON ECLIPSE", SpaceWeather.com, December 31, 2009The trendy definition of "Blue Moon" as the second full Moon in a month is a mistake.
Happy New YearBlue 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). So this is a rare event, indeed.
