The waxing moon moves eastward, passing Cancer and Leo. On the evening of April 25, the lunar orb occults (eclipses) the star Regulus for sky watchers in South America, Central America, the Caribbean basin, and the southeastern U.S. In the U.S. Central Time Zone, the occultation begins before sunset and ends during evening twilight. Farther westward, the event occurs during daylight.

An occultation occurs when the moon passes between a sky watcher and a star or planet. The eastern edge, or limb, which at this gibbous phase is dark, covers the star.

As the moon slowly moves eastward, about 0.5° in an hour, the star reappears at the bright limb. The duration is determined by the sky watcher’s location relative to the moon’s orbital plane at occultation times. The occultation can last a few minutes or over an hour, depending on the specific location.

Stars near the ecliptic, like Regulus, Leo’s brightest star, are frequent occultation targets. This Moon–Regulus occultation is the eleventh in a series of 20 that ends on December 27.

Leo resembles its mythological namesake. The head, also known as the Sickle of Leo, is made of a half dozen stars in the shape of a backwards question mark, with Regulus at the bottom. The Lion faces westward. At this season, Leo is high in the southern sky as evening twilight ends.
