July to Bid Farewell With an Illuminating Blue Moon

A blue moon, which occurs only once every few years, is set to grace skies Friday night.

However, the moon will not be cast in any colored light. Blue moon refers to the second full moon in a calendar month or the third full moon of four in a season.

The blue moon will occur at 6:43 a.m. EDT Friday, the moment the moon becomes full. However, onlookers will be able to view the moon on Friday night.

Additionally, Slooh will be broadcasting an event from the Canary Islands on Friday to discuss the blue moon.

The first July full moon occurred on July 2. Those planning on catching the next blue moon will have to wait until 2018.
