Subject: [IMO-News] Leoniden 2000

Report on Leonid observations by a meteor radar:

The Leibniz-Institute for Atmospheric Physics (IAP) operates a meteor radar
at Juliusruh (55N, 13E). If for an early evaluation, we consider only echoes
from altitudes above 100 km (characteristic of Leonids), the radar gives us
the following results:

Nov 17: A period of about 1 hour length with significantly enhanced meteor
activity occured in the morning hours with an activity peak near 08:20 UT.

Nov 18: Periods of enhanced meteor rates occured between, say 00 and 06 UT
and between 07 and 09 UT.

The short-term meteor rates where highest during the Nov 17 morning peak,
next was todays O8 UT maximum and the lowest of the three (though longer
lasting) was the 03 UT maximum.


The timing of these three activity peaks agrees well with precdictions. The
relative levels of activity do not, though. Interesting!
