Famous for producing a large number of fireballs, the Perseids meteor shower is regarded as one of the best of the year. The shower runs July 17-Aug. 24 and produces up to 60 shooting stars an hour at the peak. The shower, discovered in 1862, is produced by the comet 109/P Swift-Tuttle. A nearly full moon will cause viewing problems, but the Perseids are so bright that skywatchers should still get a good show.
