August's supermoon is the first of four lunar spectacles

Monday’s supermoon is the first of four this year. That’s when a full moon inches a little closer than usual to Earth, making it appear slightly bigger and brighter in the night sky. September’s supermoon will coincide with a partial lunar eclipse. October’s will be the year’s closest approach, and November’s will round out the year. A supermoon occurs when a full lunar phase syncs up with an especially close swing around Earth. This usually happens only three or four times a year, and the supermoons appear consecutively.
