August's full 'Sturgeon Moon' rises this weekend, putting on a spectacular lunar light show as it leaps above the southeastern horizon at sunset on Aug. 9.

The Sturgeon Moon is best seen from an elevated location, like an open field or an east-facing coastline with a clear view of the eastern horizon. While the naked eye works for this annual lunar event, binoculars or a small telescope can offer a much better view.

August's "sturgeon moon" will look largest after sunset thanks to "moon illusion," which makes the moon look larger when it's over the horizon. SAN FRANCISCO — A full moon will light up the sky in a celestial showing this weekend.
