Once in a blue supermoon happens tonight

A “once in a blue moon” phenomenon will happen on Wednesday, August 30, 2023. It will be a specifically special celestial event; a super blue moon. This is the first blue supermoon since December 2009.

What is a blue moon? Usually, a normal calendar month has one full moon. From time to time, an extra full moon will sneak in. A blue moon happens once every two to three years, or seven times in the Metonic Cycle of 19 years. (The 19-year lunar cycle is what the Greek Calendar was based on.)

What is a supermoon? A supermoon is when the moon appears unusually large in the night sky. This phenomenon is also known as Perigee when the moon’s orbit is closest to Earth. A supermoon occurs three to four times a year.
