Wed night's observations during the peak of Leonids were clouded out.
However, the meteor rate was quite low by the time the radiant had
risen. Last night the meteor rate was also low but we were successful
in probing the only two persistent trails observed visually. The
first, "Puff Daddy", was similar to last year's Glowworm although not
as bright. The Na profiles exhibited complex structure within the
meteor trail which extended over several km. Lidar tracking of the
trail continued for over 30 min. This trail exhibits features which
suggest the meteor exploded. Emission spectra and good CCD images
were also obtained. The second "French Curve" was a long sinuous thin
trail which was tracked by the lidar for about 12 min. Because the
emissions were weak and trail was thin we do not believe emission
spectra were obtained. Extensive video were obtained of both events.
