(meteorobs) Early, Hazy, Persied Results
Hello All,
Here are my early Persied results for late last
week. In contrast to other posters recently, I have been unable to get
overall rates of more than 10 meteors per hr. My skies remain hazy
night after night. No really bright meteors were seen over the three
day period. Things are looking about the same for maximum this week,
but I'll take the haze over clouds, I guess.

I was forced to cancel period 2, due to approaching clouds.
I added in the clear portion to period 1. I was not fortunate to
obtain the high rates reported by others for this date...perhaps it was
my poor
LM's due to the haze, or latitude.(?) Persied rates did overtake
sporadic rates for the first time in my observations this month.
Outbursts, Everyone, Kim Youmans
