Walt Heiges with the Sacramento Valley Astronomers Society says the supermoon phenomenon happens when the full moon is closer than usual in its orbit.

Depending on where it is in the sky, a supermoon can play tricks on your eyes.

The first of the three supermoons appeared early on Saturday, July 12. If you missed it, you can catch the ones on Aug. 10 and Sept. 9.

Also watch out, supermoons usually bring higher tides.
