For the second time this summer, a “Super Moon” popped up. A “Super Moon” is a phenomenon that occurs every 14 lunar cycles when the Moon reaches its perigee at the same time it’s full. As a result, it appears significant larger and brighter than it normally does.

This past weekend, the “Super Moon”—the second one of 2014—was extra super. As Nat Geo says, the “coincidental timing of the moon being at its closest approach to Earth for 2014, at 221,765 miles (356,896 kilometers) away” at the same time it’s full caused it to look 16 percent larger and 30 percent brighter than normal.

The next one—and last one of the year—will occur on September 9. Best get your affairs in order.
