August 7/8 to 23/24 Meteors

Hello everyone!

I’m back from a few relaxing weeks visiting family and friends in Italy. Since it has been a few weeks since my last post, I will try to catch up with the latest meteor and comet news.

I debated whether to leave my cameras up and running while I was gone. The MetRec software that I use for meteor detection is more than capable of running autonomously for long stretches of time. If it had been any time of the year other than summer, I would have done that. But August is still hot in Tucson with temps still routinely hitting 100+. Since my computers are located in a non-temperature controlled room that can get very hot, I decided not to push my luck and risk coming home to 2 cooked computers.

This means I missed a great Perseid display (I’ll summarize what others saw in a later post). Luckily Bob Lunsford’s camera was up and running. He was able to catch one of the 2 big Perseid peak nights.

Bob’s notes from the night of August 11/12: “I took my system to dark skies near Alpine, CA to view the Perseid maximum. I managed to record 176 meteors during the 4 hour session. This included a slight outburst near 1am PDT when the Earth crossed particles produced in 1610 from the Perseid parent comet Swift-Tuttle. The counts could have been more had it not been for cirrus clouds present during the first hour of the session and bright moonlight, which was present all 4 hours.”
