LOS ANGELES, Calif. (CBS, KYMA/KECY) - August's first full moon, also known as the "Sturgeon Moon," will shine brightly in the sky on Tuesday night.
It will appear brighter and bigger than the average full moon. The August 1 full moon is the second of four consecutive supermoons, which occur when the Moon's orbit is closest to Earth at the same time the moon is full.
Supermoons are about 16% brighter than an average moon. The supermoon will be even closer on the night of August 30 because it will be a rare blue moon, which occurs when there are two full moons in a single month.
A blue moon is not blue in color, according to NASA. Astronomy fans only get to see blue moons about once every three years on average. The next blue moon after the one on August 30 will be in May 2026. The last of the four consecutive supermoons this year will be the September 28 "Harvest Moon."
