A strange thing happened with us during our observing meteors by
radio. On 7-8 September 1998 from 22:44-03:00 UT, with an effective time
of three hours, we heard 173 meteors, actually that was our first
experiment in observing meteors by radio, so I thought this is the
normal average of meteors. But later on, we held other observations, but
never reached that number that we achieved in our first experiment (173
meteors in three hours) ! Knowing that we used the same equipment and
frequency, the only difference was our location, however during the
Draconids shower we were observing close to our first location (around
30 Km away only).<<
Perhaps you were hearing the peak of the delta Aurigids? They peak on the
night of Sep 7/8. When you listened on another day, the peak was no longer
there and you were hearing lesser rates.
Mohammad>> Knowing that, even on 7-8 Sep., at first hours there was no high
activity of meteors ! the activity increased suddenly around 22:30 UT
(Which is 01:30 Local Time)! <<
In the early evening you should hear less meteor activity than you would after
midnight. When I use to monitor meteors on radio while simultaneously
observing visually, on nights were no major activity was occuring, I would
hear about 6 meteors/hour near 6 pm. Around midnight I would hear about
20-30/hour. Then around 6 am I would hear the most activity...often close to
45-60/hour.
