(meteorobs) re: NAMN Meteor Report: Nov 16/17 (HALWA)
To all,
I noted a typo while researching that last lewquery in my report. In the
attachment to my report entitled temporal and magnitude distributions, the
first period should be from 0530 to 0725. Second period starts at 0735 so
it should have been obvious.
total time below is 0530 to 1040.
SSSleepless night still catching up to me I guess
So sorry
Thanx Lew
Wayne

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.
