Sep 18 – 31 Meteors

It has been a long time since I posted my nightly video meteor results. Part of the problem was our annual monsoon season here in Tucson. But the main problem was a series of mechanical and software issues that I just didn’t have the time to solve until a few weeks ago.

The 2011 monsoon was very similar to last years ‘nonsoon’. Though every night saw lots of clouds and rain threatened, little rain actually fell. That wouldn’t have been too much of a problem for my video set-up except for the fact that my ‘all-weather’ camera enclosure is no longer ‘all-weather’. So I decided to leave my camera off on those nights when it looked like it might rain. Since I was going to be down for weather reasons anyway I went ahead and upgraded to the latest version of the automatic meteor detection software, MetRec. That didn’t go so well and resulted in finally upgrading from an old PIII computer to a Pentium 4 machine. Now, knock on wood, everything seems to be working.

September is a month of high meteor rates. Sporadic meteors rates are near their annual peak. Though no major showers are active, a number of minor showers are consistent contributors to the high rates. Below are a collection of some of the best meteors from the last two weeks of September.

    I noticed an outburst of Delta Aurigids the 23rd into 24th. With in a minute i viewed 5 nice meteors all coming from the same radiant.
