The half-lit moon is upon us! Here's what to expect as Earth's natural satellite reaches its third quarter phase early on March 11, how to see it and what to look out for on its ancient surface.
March's third, or final quarter moon phase will occur at 5:39 a.m. EDT (0939 GMT), as the moon appears in Earth's sky with its left half illuminated by direct sunlight and its right masked in shadow, close to the stars of the constellation Scorpius.
