Re: (meteorobs) No Quadrantid Peak From MI/Quadrantid Flashes?



Mark and everyone,

          It wouldn't be necessary for the flashes you describe to be near
the radiant for them to have been Quadrantid fireballs.  But  the date of
your observation (Dec 31/Jan 1) makes that less likely.  Minor shower or
sporadic fireballs, or some other source, would be far more likely in my
opinion. On peak nights for major showers, it's not unusual to see bright
flashes light up the ground or trees but never actually see the source.  I
personally saw pine trees "light up" very quickly Friday night and had an
independent witness.  I also saw  -2 and -1 "*fireballs*" right at the
horizon -- given magnitude extinction at that elevation, no doubt these
would have bee quite impressive had they appeared overhead!
          Keep up the good work, Mark.  One night you're going to see a
bolide's terminal burst light up the entire sky with glory and you'll be
genuinely hooked on meteor observing!
