Look for a Blue Moon on Thursday, Friday

August 29, 2012|By Scott Dance, The Baltimore Sun

By most people's definition of the term, a Blue Moon arrives on Friday. But you can look for its bright shine Thursday night, too.

It is the second full moon of this month -- the first was Aug. 1, the Green Corn Moon. Commonly, since this full moon falls before we say goodbye to August, it's known as a Blue Moon.

The moon reaches its "full" phase at 9:58 a.m. Friday, making both Thursday and Friday nights about equally good for photo opportunities or moonlit walks. Clear or only slightly cloudy skies are in the forecast for both nights, too.

There won't be another month with two full moons again until July 2015.

If you go by the Blue Moon definition that dates further back in history, however, this full moon is nothing special. By that rule, the third full moon in a season with four full moons is considered blue. That would mean some might call this full moon the Full Fruit Moon because it's the last before the autumnal equinox.

The next times Blue Moons will come as the third out of four in a season will be Aug. 21, 2013, and May 21, 2016.

Luckily, the full moon looks just as beautiful by either definition.
