Sounds like Kim's experience was similar to mine other than I didn't
quite get the -5s. But I got 5 hours Teff between 04:00-09:40 UT; like Kim
the first hour was easily the best, with about 50 meteors, probably 10 of
them in the (low) negative magnitudes. Excellent results for 9-10 p.m.!
Rates steadily diminished from there, but it was a very good night. I will
transcribe my tape and report in detail as soon as I can. I have three
Geminid sessions to catch up!
