Last night, on September 19, 2025, the moon was in the Waning Crescent phase. It was about 27 days old in its lunar cycle with only about 5-7% of its surface illuminated. This phase occurs when the moon is getting closer to the sun again, and the visible illuminated crescent is shrinking. The best time to view this phase is just before sunrise, with the crescent appearing in the western sky. The moon was nearly invisible to the naked eye due to the small illumination percentage.
