We had partly couudy to mostly cloudy conditions all
night. However, I was lucky to catch an all clear sky
during the last hour of full darkness for the Perseid
maximum. With a LM=6.5, and 20% obstruction, facing
NNW, away from the moon, from 7:55 to 8:55 UT I saw
73 Peresids! There were several bright ones, including
a -4 Perseid seen at 8:41 UT with a 33 second train, a
-3 Peresid seen at 8:45 UT, a -2 Peresid seen also seen
at 8:45 UT, and another -3 Peresid seen at 8:47 UT, all
with nice trains! This is my best Perseids in 12 years!

I was able to get two more good hours in on Monday, but
the rates were about half as much for the Perseids, but
still a respectable 34, and 35 per hour repectively,
from 6:45 to 8:45 UT. There were no Perseids seen that
were brighter than -1 that morning. The average Perseid
brightness was 1.7 on the 12th and 2.4 on the 13th with
similar observing conditions. See more details below.
