(meteorobs) Mt. Lemmon (Arizona) preliminary Leonid plots posted
Hello all,
Some *preliminary* Leonid rate plots from the Mount Lemmon, Arizona,
Leonid-MAC observing team have been posted on the American Meteor Society
website
http//www.amsmeteors.org/
I would like to express my thanks to the entire Mt. Lemmon team,
especially those observers who travelled from throughout the southwest to
participate in this campaign. Everyone worked very hard and with little
sleep to bring about a very successful operation. Our final team
consisted of
Matt Chamberlain -- Tucson, AZ
Kenneth Frank -- Tiburon, CA
Robin Gray -- Winnemucca, NV
Rick Greenberg -- Tucson, AZ
Lyn Kogler -- Tempe, AZ
Tom Kucharski -- Mission Viejo, CA
Huge Murray -- Tempe, AZ
Jim Richardson -- Tucson, AZ
From our perspective, the second predicted Leonid peak was very sharp
and a little bit late (1054 UT +/- 007). This portion of the shower
was rich in faint meteors (R = 3.5-4.0, small sample calculation) and
quite sparse on the bright end of the spectrum. If it had not been
for the interfering moonlight, the show might have rivalled last year's
(from the same location). As it was, we reached a maximum ZHR of
about 650-700 m/hr, with limiting magnitudes in the 5.0-6.0 range.
We also experienced a secondary peak of ZHR = ~200 m/hr at around 1151
UT, and I am curious to see if observers in other parts of the country
also experienced this (or was the effect purely local).
Best regards,
Jim Richardson
