(meteorobs) Aug 12/13 Perseids success from Western Quebec
Hi all,
I haven't decoded my tape yet, but here's my impressions of last
night...
Last night I travelled to an unpolluted site located two hours north of
Ottawa to catch clear skies. It was a successful night. Good
transparency at the zenith for such a moonlit sky (LM=5.2 to 5.4 or
so), with the exception of about one hour of a thin sheet of clouds
after midnight.
While setting up still in very bright blue evening twilight here (near
21 EDT or close to 1 UT) it appeared some impressive earthgrazing
Perseids. Very bright and long meteors! It surprised me to see them
by just quick glances up since I wasn't ready to start until the sky
got reasonably dark. Could this have been the "tail end" of the
possible 0 UT feature? It seemed that as the sky got darker and
radiant rose higher, that the Perseids were on a decline.
After midnight and up until about 0300 EDT, there seemed to increase
again. Even with the temporary blanket of clouds, quite a few bright
colorful meteors pierced right through! After that, despite the
radiant approaching the zenith and lower moon, the Perseids seemed to
be declining quite steadily.
This year, Perseids seemed a good mix of both faint and bright meteors.
There was a few nice colorful fireballs... the best was right before
morning twilight when a magnificent long magnitude -6 Perseid plunged
to the north-east with a terminal explosion, followed by a train
glowing and twisting for several seconds!
I need to catch up on some sleep now. Stay tune for my full report
later today.
