We formed a circle of chairs and began to study our assigned areas of the sky for meteors. It started off slowly, about 30/hour. After 3 hours it picked up dramatically, and we observed a peak of about 40/second that lasted for 10 to 20 minutes. This was 24,000 in a ten minute period, a rate of 144,000/hour. We stood in awe as the sky seemed filled with
