Perseids

One of the best meteor showers is Perseids in August. In 1991 and 1992, outburst activity was obeserved by the return of paranet comet. It is easy to observe because Perseids provides a lot of bright meteors.
In Radio Meteor Observation, Perseid activity is caught every year. Since the geocentric velocity is too fast as 59km/s, it is no much meteor echoes. On the other hand, a lot of long echoes more than 20 seconds are caught. In 2004, Lyytinen et al. predicted the outburst of Perseids. Radio Meteor Observation was also able to observe this outburst cleary as same as visual observation.
