Skywatchers are in for a treat on Monday morning as the full Worm Moon will be partially eclipsed by Earth's shadow, creating a subtle penumbral lunar eclipse.

The moon, reaching peak fullness at 3:00 AM ET, will be adorned with the traditional name "Worm Moon" according to the Farmers' Almanac, reflecting the emergence of earthworms and other creatures from winter slumber.

A few hours earlier, at 12:53 AM ET, the celestial event begins. The Earth, Moon, and Sun will align near-perfectly, causing the Earth's outer shadow, called the penumbra, to fall upon the moon's surface.

A Subtle Shift in Light

The peak of the eclipse occurs at 3:12 AM ET, when the moon may appear slightly dimmer than usual, explains Dr. Shannon Schmoll, director of the Abrams Planetarium at Michigan State University. "It'll be a gradual darkening from one side of the moon to the other," she says, "not a dramatic change."

However, attentive observers might notice these subtle variations in brightness.

The Worm Moon, named by Native American tribes, will be visible worldwide for a few days surrounding its peak fullness.

However, the penumbral eclipse will only be observable to those on the night side of Earth during the event, encompassing regions like Europe, North and East Asia, Australia, Africa, North America, and South America. The eclipse concludes at 5:33 AM ET.
