(meteorobs) East GA Geminids >100/hr 12-12/13-2004

[Kim Youmans]

        I was fortunate to again find crystal clear skies at my site this 
morning and had a great three-hour session.  The Geminids flew fast and 
furious, especially during the third hour (2:00-3:00 AM local) when 102 
Geminds were logged!  This is the first time I've ever logged more than 100 
non-Leonid shower members in a single hour and could well be my best 
non-Leonid hour ever.  The first two periods saw 86 and 91 GEMs, 
respectively.  In all I logged 308 meteors in exactly 3.00 hrs teff.
        I was pleased to once more have several negative magnitude Geminids, 
including a -4.  I noticed while writing up my report I was biased against 
+4 magnitude meteors -- there's a substantial gap between the +3 and +5 
column.
I plan one more trip out to my site again tonight, from 9:00 - 12:00 local 
time, maybe as late as 1:00.  It has been unbelievably clear here for the 
Geminids and I'd be willing to bet it will be many, many more years before I 
get as good a seat as I've gotten this time around....  (Note: 5-minute bins 
at very end of report)
