SAN ANTONIO -- The full moon on Saturday will be a "supermoon" -- the first of three this summer.

"Supermoons" happen when the moon's orbit brings it closer to Earth.

The best time to take photos is at moonrise, The Washington Post writes, when the moon appears largest. That's because of the Ponzo Illusion, in which the mind tricks itself into thinking objects are larger based on their surroundings.

There will be two other supermoons this summer on Aug. 10 and Sept. 9.

Moon watchers in San Antonio should have a clear view Saturday night. A National Weather Service spokesman said there will be few clouds that should clear out by moonrise, which will be at 8:48 p.m.
