Each summer, skywatchers around the world look forward to the famous Perseid meteor shower, but often overlook four lesser showers that peak between July 29 and Aug. 16.

On July 17, the Perseid meteor shower begins just as the last quarter moon rises, but its peak night in August will be marred by moonlight.

The first meteors from two showers — the Delta Aquariids and the Alpha Capricornids — began streaking across the sky on Sunday, July 13. The shows will get more intense during the second half of July, peaking on July 30.
