Moon Phase: May 20, 2021

On this day the Moon was in a Waxing Gibbous phase. Visible through most of the night sky setting a few hours before sunrise. This phase is when the moon is more than 50% illuminated but not yet a Full Moon. The phase lasts about 7 days with the moon becoming more illuminated each day until the Full Moon.

During a Waxing Gibbous the moon rises in the east in mid-afternoon and is high in the eastern sky at sunset. The word Gibbous first appeared in the 14th century and has its roots in the Latin word "gibbosus" meaning humpbacked.
