Earthshine Moon with Mercury and Venus (after sunset)

The western sky after sunset on Saturday, March 1 will provide us with a spectacular sight and a lovely photo opportunity. The sliver of a crescent moon will shine below Venus and above Mercury. Venus and the moon will linger for about an hour longer after Mercury sinks below the rooftops around 6:30 p.m. local time. Keep an eye out for Earthshine on the moon. Sometimes called the Ashen Glow or the Old Moon in the New Moon’s Arms, the phenomenon is visible within a day or two of new moon, when sunlight reflected off Earth and back toward the moon slightly brightens the unlit portion of the moon’s Earth-facing hemisphere. A backyard telescope will reveal that Venus also has a crescent phase while Mercury will show a gibbous shape.
