The Perseid Meteor Stream
The Perseid meteor radiant shows unusual mobility and descends across more than 50° of arc from moderately high elevation in the east towards the northeast between about July 25 and August 17, moving from about 2°RA 41°Dec in Andromeda across the celestial N of Perseus to 68°RA 61°Dec in Camelopardus, reaching a maximum of around 50 particles per hour around August 10-12 and dwindling rapidly over the next five nights or so. On the night of August 13-14 the shower has passed its maximum and the radiant is only about 10° of azimuth from its terminal position in the NNE. [Tver, Motz & Hartmann, 1979]
