REMARKS: Seeing throughout session was medium to medium-poor.
Dead time of 45 seconds was deducted per plotted meteor.
Meteor #1 was noted as a possible Aquillid (non-IMO shower).
Meteor #3 was noted as an (unlikely!) Aquillid (non-IMO shower).
Meteor #4 was noted as a possible JLY (non-IMO shower).
Meteor #5 was noted as possibly from a new radiant near Xi Dra
(non-IMO shower). Length and path are close matches, although
speed (medium-to-medium-slow) may not be: meteor was close to
radiant, however, so apparent speed may not be a determinant.
Meteor #7 was noted as an (unlikely!) JLY (non-IMO shower).
Meteor #11 was noted as a possible JLY (non-IMO shower).
At 0615UT a mag=2 speed=2 "dark meteor" was observed traversing
the Milky Way in Cygnus. (Naturally not plotted).
The "mins in effect" column in the limiting magnitude estimate table
is merely designed as a computational aid for this observer (and as
a later consistency check for users of the form) as to how much time
the given magnitude estimate(s) were in effect. It can be ignored in
analyzing the estimates themselves.
A very interesting night's observing.
