Subject: (meteorobs) IMO METEOR SUMMARY REPORT, 15/16-
Dec-2001, GRALE
>
>Here's a more timely report on the Geminids... Still
impressive rates this
>night from the GEMs, even two days after their peak.
But the fainter GEMs
>had begun to predominate, of course - and note that
rates were declining.
>
>Anyway, in any normal year the Geminids really are my
favorite shower. It
>is just too bad that I rarely get to see their
maximum from up here! :(
>
>Thanks to Bruce Berger and Mike Aramini of ATMoB for
"keeping me company"
>on the lawnchairs while I did these counts. Meteor
observing can be even
>more fun, when you do it in a small and interested
group, for sure!
