Pegasids
The meteor shower of the Pegasids occurs between the 7 and 13 July. It is a weak meteor shower that has its maximum around July 9 having a ZHR of only 3 meteors per hour. The meteors have, however, an atmosphere entry speed of about 70 km/s.
The Radiant of the Pegasids is in the constellation of Pegasus, around 5 degrees to the west of the star α Pegasi. The origin of this meteor shower is probably the comet C/1979 Y1 (Bradfield).〔(Meteor Data Center )〕 C/1979 Y1 has an orbital period of 300 years.〔http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=1979Y1〕
For Central Europe, the best time to watch them is the second half of the night, as the radiant reaches at that time a sufficient height over the horizon.
