(meteorobs) Observation August 14/15 2013

[Pierre Martin]

I went to Bootland Farm on Thursday morning to check out Nova Delphini and observe the post-max Perseids (PER).  Sky was very nice (3/5 trans, mag 6.5-6.6), clear, 12C, a light breeze and no bugs.

I signed on for meteors at 2:10am (local time) and watched for two hours.  It was actually a rather entertaining session with 67 meteors.  Nowhere near the rates of last Monday morning, but with a lower expectation away from the peak, I was pleased.  The PER were evidently on their declining slope, but still active enough to be the main shower activity with 28 of them seen.  The brightest PER was a long mag -2 that left a 5 sec train.  Other showers were active in small numbers, and I was surprised to see a few late Delta Aquariids.  It's like they don't seem to want to give up.  The Eta Eridanids were also fairly active with a few very swift meteors.  The brighter ones appeared blue-green and were usually trained.
