The Blue Moon in 2023 occurred on August 30-31. It was a rare event known as a Super Blue Moon, meaning it was both the second full moon in August (a Blue Moon) and also a supermoon, when the moon is closest to Earth and appears larger and brighter. The exact moment of full moon was at 9:36 p.m. EDT on August 30, 2023, and it rose just after sunset that day. This was the last Super Blue Moon until 2037.
