(meteorobs) 1999 South Ga Perseid Results



Hello All,
           With all that data from the recent perseid shower piling up
on my desk, and the moon reaching its full state, I decided to sit down
and crunch a few numbers.   I herewith respectfully submit a brief
outline of my Perseid observations.
           Overall, weather wise, I was more fortunate than many on my
side of the Mississippi,  with thick haze being my worst enemy on most
nights.  But my rates were nothing short of pitiful--still, after
watching sporadics for most of the year, I had a great time, sleep or no
sleep!
I enjoyed many small bursts of activity, including an early one on the
night of
9/10 at around 8:30UT.  My LM's were right at 6.0 for local maximum, so
I didn't complain.

   Time is Universal Time.  PER is total perseids per session. Teff is
total Teff per session.  LM is the average limiting magnitude for the
entire session, regardless of # of hours.  Sporadic activity has been
omitted.  I faced South or SE each night at an elevation
of about 65-80 degrees.

Average OHR is derived from the numer of perseids per a given period
divided by the teff for that period, all periods being averaged together

for the final result.
