“On average, we have one full moon per month, but since most of our months are a little longer than the lunar cycle, this means that If we end up having a full moon at the beginning of the month, we may have another full moon at the end of the month. This is called a blue moon. In one season, which is about three months long, we typically have three full moons, and If we get four in a season, the third of the four will be a blue moon.“This is a blue moon,” Shannon Schmuhl, director of the Abrams Planetarium at Michigan State University, told CNN.

The next supermoon of the year will be visible on September 18, October 17 and November 15. The next lunar event that will combine these two events is scheduled for January and March 2037.
