The moon out tonight, September 20, 2025, is in the Waning Crescent phase. It is very close to the New Moon phase with only about 1-2% of its surface illuminated as seen from Earth. The Waning Crescent moon is best viewed just before sunrise in the western sky, and its illuminated portion is shrinking each day as it moves closer to the New Moon. This phase shows only a small crescent edge lit, with most of the moon's night side facing Earth, making the lunar surface features easier to observe with telescopes or binoculars due to the long shadows cast along the terminator line.
