REMARKS:
Note 1 : These 3 Meteors were definate Leonids, however radiant was below
the sickle slightly...enough to be commented on.
Note K : Kevin Kilkenny may have photographed these meteors.
Note 2 : I did not directly observe this meteor. Magnitude estimate is based on
ambient illumination.Probably more accurate than if I had seen it. When I
turned 3 seconds later illuminated train was visible below Cassiopeia,
giving accurate confirmation as Leonid. Visible for 7 1/2 minutes, smoke
train sheared to west, quickly at top, more slowly at bottom. Sketch on
gnomic map will be included with Novembers plots.
Note 3 : Possible DPU or ZPU
Note 4 : Meteor had 2 trained segments, a shorter yellow -2, then a longer
yellow -2 punctuated by -4 blue burst in middle. These two segments were
separated by a 0 mag, untrained gap.
Note 5 : Path plotted on Gnomic maps.
Note 6 : Detailed temporal and magnitude distributions of LEONIDS and
SPORADICS will be included below.
