Tonight's full moon is a special one: it's the only Blue Moon of 2012, with the next occurrence not coming until July 2015.
What is a Blue Moon? According to the American Heritage Dictionary, there are a few possible definitions...
In tonight's case, it is the second full moon in August, but this definition is actually not preferred by the experts over at Sky and Telescope Magazine. Click here for the full scoop on how a mistake made in 1946 led to the current (and "inaccurate") definition of a Blue Moon.
Last night's moon was so bright I could have read a book outside, and tonight's moon promises to be even lovelier. In case you're in the mood, here's the recipe for a Blue Moon Cocktail:
2 oz dry gin
1/2 oz freshly squeezed lemon juice
1/2 oz Creme Yvette (or creme de violette)
Fill a mixing glass two-thirds full with ice. Add gin, lemon juice and Creme Yvette.
Shake vigorously and strain into a martini glass.
Enjoy while watching a Blue Moon.
