The Sky Tonight Update: Full Moon, Blue Moon
The Moon will be located on the opposite side of the Earth as the Sun and its face will be fully illuminated. This phase occurs at 08:46 UTC (02:46 AM CST). Since this is the second full moon in the same month, it is sometimes referred to as a blue moon. This rare calendar event only occurs one every few years, giving rise to the term “once in a blue moon.”
