(meteorobs) YOUKI Leonid report, 11-18/19-2002

 East GA, USA

I was forced to abandon my newly-selected site due to clouds at 12:30 EST

last night, but within 30 seconds I was pretty much cloud free at my second

site.  I was hampered by fog at around 9:35 UT for ten minutes or so but it blew on

out rather quickly and clear skies became the rule again.  The moon sank and

my LM's improved to a fairly respectable 5.5 on average most of the night.

The night began slowly, and it reminded me of 1999, rates were dependent

on the radiant rise and nothing else, until I began my fourth period at 09:05 UT;

rates slowly started to climb.  There were a few scattered fireballs -- I did have -7,

a -6, a -4 ... but the dim meteors far outweighed the rest.

When the peak did kick in, it was astounding at times, with several simultaneous meteors,

the wheel spoke effect, and sometimes 6-7 meteors appearing within seconds.

The meteors were quite colorful, with blue and green dominating.

My highest minutes were at 10:39 (16 meteors), 10:42 (16 meteors), and 10:48 (15 meteors).

All told, I saw 438 meteors from 6:00UT until 11:08 UT

Given the poor LM's, this would have been some treat under a +6.5 sky!!!

With this peak, I Ihave now been fortunate enough to see all the peak returns

of the Leonids since 1997, except for 2000.

 

Please find my one-minute counts at the end of the report
