On August 10, the Moon passed in front of the triple star system, Pi Sagitaurii star system. The even was captured by Efrain Morales Rivera from the Jaicoa Observatory in Aguadilla, Puerto Rico. "An interesting event, capturing this triple star system being occulted by the Moon and 1 hour and 26 minutes later re-appearing on the bright side of the moon," Rivera wrote to tell us.

He even created an animation of the stars "winking out," as seen below.
