July 31 – Aug 5 Meteors

The monsoon wiped out the first three night of August. Happily, these clouds did bring a bit of rain.

The nights of August 4-6 UT were very disappointing for my meteor detection network. Early August is a busy time for meteor watching with the Perseids (PER) ramping up and the various Aquarius (SDA,SIA)/Capricornus (CAP) showers still producing. I fully expected to be detecting many 10s of meteors per night rather than the lowly 20-21. At that rate, I wasn’t detecting any more meteors than back in late June.

Turns out it was a bit of an upgrade issue. The night of July 31 saw me using the newest version of MetRec (the automatic meteor detection software I use). At first I thought my camera was on its last legs as these cameras are known to loss sensitivity with time. As it turns out, one of the configuration files for MetRec got confused resulting in the software shutting down 2-3 hours before dawn. Since the last hours of the night see the highest meteor rates, it really put a dent in detections. As of August 7 UT, the problem has been fixed.
