(meteorobs) IMO METEOR SUMMARY REPORT, 12/13-Dec-2000, GRALE
Here is the first full report I will have gotten into IMO and NAMN this year!
I'm posting this long form to the entire 'meteorobs' list, partly to stimulate
some questions, and partly as an encouragement to myself and others (you know
who you are!), to complete all the OTHER full IMO reports from our observing
sessions during this past year...
Note that the highlights of last night for me were both the unexpectedly high
pre-midnight activity from the Geminids, and a lovely -3.5 GEM terminal-burst
fireball, low in the WSW at 6:37UT, which changed colors from yellow to lovely
blue-white just prior to its terminal burst.
If anyone on our 'meteorobs' list has any questions about the following report
(e.g., "What the heck do all those NUMBERS and CODES mean, Lew???"), please DO
NOT hesitate to post such questions to the 'meteorobs' list at:
meteorobs@jovian.com
BTW, soon to follow will be the first *EVER* IMO Summary Report from my fellow
Boston-area meteor observer, Rachel Aubuchon, for the Leonid outburst of 17/18
November! I'll be sending that along some time before the coming weekend. And
at some point very soon after that, my own Leonid outburst Final Report, as
well as Rachel's IMO Report on last night's activity will follow.
Clear skies and many meteors!
