A rare lunar phenomenon will appear in the night sky this weekend as a Blue Micromoon reaches its full phase on May 31, 2026. The event blends two different moon occurrences into a single full moon, making it one of the most fascinating astronomical sights of the year for skywatchers around the world.
As per the Science Alert, a Blue Moon refers to the second full moon happening within the same calendar month. A Micromoon, meanwhile, occurs when the Moon becomes full while placed near apogee, the farthest point in its orbit around Earth. Because of this greater distance, the moon seems to be slightly smaller and dimmer than a normal full moon.
