The Moon’s current phase for today and tonight is a First Quarter phase. This phase occurs roughly 7 days after the New Moon when the moon is one quarter of the way through its orbit around the earth. Exactly half the moon will be illuminated and half dark. On the day of the First Quarter phase the moon is high overhead at sunset and is visible until mid-night when it sets in the west. The First Quarter phase is a one-day event and in the following days enters a Waxing Gibbous phase becoming more illuminated each day until the Full Moon.
