The largest full moon of 2013 will appear in the sky this Sunday, Jun. 23. Skygazers with cloudy or obstructed views can tune into the live stream below.

The "supermoon" occurs only once each year, when the lunar perigee (the point at which the moon is closest to the earth in its orbit) coincides with the full moon. The moon will be only 221, 823 miles (356,991 km) from the earth -- 17,000 miles closer than average, and will appear about 12 percent larger and 30 percent brighter than usual in the sky.

This effect will be magnified when the moon is close to the horizon, so try to snap those pics close to sunrise.

The closeness of the moon should also cause slightly stronger tides, both high and low, for a day or two after the supermoon.

The live stream of the phenomenon will be broadcast at 9 p.m. EDT (6 p.m. PDT) Sunday night. Don't miss out, since the next supermoon won't occur until August 2014.
