Every few years, one month has two full moons. July 2015 is one of those months. This Friday, July 31, you can witness the month’s second full moon, also now known as a Blue Moon.

Don’t be disappointed, though, if the sky isn’t glowing in blue light. The name’s origin has little to do with the color. (Learn more about where the name comes from.)

Whether or not you believe full moons hold magical properties, just their luminosity alone holds advantages. Exploring one of Mass Audubon’s wildlife sanctuaries with a naturalist under a moonlit sky brings one in touch with the animals that prefer to live on the edge of day and night such as emerging owls and foxes, foraging deer, and more.

So why not take advantage by getting outdoors or joining us for a evening program this Friday night.

Just chalk it up as something you really do “once in a blue moon.”
