Tonight, August 17, 2025, the moon is in its Waning Crescent phase. Approximately 35% of the visible lunar disk is illuminated by the Sun, and the moon's illumination is decreasing as it moves towards the New Moon phase, which will occur in about 6 days. The Waning Crescent phase is best viewed just before sunrise in the western sky. So, you can expect to see a crescent- shaped moon with less than half of its surface lit, gradually getting smaller each night until the New Moon.
