Activity from this meteor shower is visible from about July 23 until August 22. At the time of Maximum on August 12/13 (J2000 solar longitude=139.7 deg), the radiant is located at RA=47 deg, DECL=+57 deg. The hourly rate typically reaches 80, although some years have been as low as 4 and as high as 200. The meteors tend to be very fast, with an average magnitude of 2.3, and about 45% leave persistent trains. The radiant advances by a rate of 1.40 deg/day in RA and 0.25 deg/day in DECL.

You probably know quite a bit about our solar system already. Perhaps you've seen shuttlecraft launches on TV or the movie Apollo 13 and have become interested in the people and spacecraft that have helped us study the Earth and the Moon. Maybe you've read books and magazine articles about the nine planets, the Sun, and the space missions that have gathered information about them. But did you know that one of the best places to find facts, pictures, and movies about the solar system is on the Internet
