The meteor shower of the July Pegasids occurs between July 4 and Aug 8. It is a weak meteor shower that has its maximum around July 11 having a ZHR of only 3 meteors per hour. The meteors have, however, an atmosphere entry speed of about 64 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).[2] C/1979 Y1 has an orbital period of 308 years,[3] and should return around 2287.

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.
