I had a great night watching Perseids. (Though I am jealous about Wes and others
at the Oregon Star Party DARK SKIES there.)
This is data for the first hour I watched.
A second hours set of data (10:13-11:14UT) will follow later.
Between the 2 data hours my 12 year old son Jordan came out and we saw a -3
Perseid with a double burst of intensity very cool.
