(meteorobs) Leonid Report: East Central GA

     What started out slowly, without promise, wound up being one the best meteor-observing nights I've ever had.  I knew of the European storm before I went out to my site,
but grew patently discouraged when, after two hours and Leo rising right on up into the sky, no Leonids were seen, at all.
     Period three, however, yielded 19 leonids.  The count grew each hour as the radiant climbed higher, the hourly rates becoming 19, 27, 41, 61 -- period 6 was divided up into two periods, a (Teff=1.0) and b (Teff=.5) of 61 and 30 meteors respectively.
     During the last 40 minutes, I was seeing better than 1 meteor per minute.  Not the great, fantastic night I had hoped for, but all in all, a very excellent night of observations.
The brightest meteors were all primarily Taurids, with the Leonids on the dim side, though I had quite a few +2's.
