Blue Moon Over the Hudson Valley, July 2015

Taken by John Morzen Photography

"The blue moon made its appearance over the Hudson Valley on Friday, July 31st. A 'blue moon', by definition, could be the fourth full moon during a 3-month season, or the second full moon in any given month. Friday's was the latter definition, and the night was absolutely gorgeous - completely clear sky, warm breeze, and all.

A friend and I headed down to the Hudson River before midnight and spent some time talking, taking in the moonlit landscape and get some photos - this was one of them.

The term 'Once in a blue moon.' is an expression for something that doesn't happen often, and with good reason - the next blue moon won't be until January 31st, 2018. As for the next blue moon to appear during the summer? That won't be until August 31st, 2023. Let's hope it'll be another clear night!"
