[AZ-Observing] Re: Preliminary Results from Mt. Lemmon



Except that their "all-sky" count is fed to a computer program that
should reduce the raw observer data to a calibrated ZHR rate.  The
question is the definition of ZHR and how it is applied to the data.

There was a wink after my statement, that did represent a little
sarcasm, and that data should always be suspect.  Our one minute counts
(for a single observer) did estimate rates of a couple thousand an hour
for a short period (10-20min).  There were moments when five to ten
would happen so fast you could barely register tham all as your eyes
jumped about the sky.  This agrees with what the observers on Mt.
Lemmon, a few miles away, show in at least the broad strokes.  Either
way I am more than glad that I observed the show!

I have yet to see any results from central Asia or Australia. Photos
Monday, no one-hour photo, these go to a proper lab that can handle the
push processing correctly.
