Perseids Meteor Shower (Peak Time and Condition)

Pocket

Perseids in August is one of the best meteor showers. In 1991 and 1992, outburst activity was obeserved by the return of paranet comet. It is easy to observe in visual because Perseids provides a lot of bright meteors.
In Radio Meteor Observation, Perseid activity is also possible to catch clearly every year. Since the geocentric velocity is very fast as 59km/s, it is no much meteor echoes comparing with visual observation. On the other hand, a lot of long echoes more than 20 seconds are caught. The maximum both visual and radio occuer around λ=139°.9-λ=140°.0.
