Here’s a pre-peak Perseids watch for the morning of August 11 2016 at Bootland Farm. Sky had average transparency but with some cirrus clouds covering the north. It was a warm night at +20C and very humid but without any dew. I was excited when I got out of the car there, as a nice mag -2 Perseid shot to the north! It was a surprisingly noisy night with a lot of crickets all over the place 🙂
I observed for two hours, from 3:30-4:32am and I saw 68 meteors. The Perseids were going on strong in the first hour with 35 seen, but for some strange reason, the rates dropped to only 16 in second hour. I can’t really explain why that occurred as I was fully awake. There seemed to be more very faint meteors in the second hour too.
The best meteor was a Perseid at 3:08am that shot over 30 degrees and flared to mag -3, leaving behind a 4 sec persistent train!
At 3:03am, a sporadic and anthelion appeared exactly at once and nearly crossed paths.
Another highlight at 3:26am : a highly foreshortened blue-green Perseid near the radiant that flared to mag -2, and left a 2 sec train.
Unfortunately, the peak night August 11/12 of the Perseids was a washout. I made an effort to chase “sucker holes” to the east of the city, and then to the south-west. The best I managed was seeing a pair of meteors through a very small brief opening. The following night August 12/13, Shane Finnigan and I drove to the Plevna and Nirvana sites to try and catch an opening between clouds, but we got caught in a heavy rain as we waited in the parking lot at Plevna. At Nirvana, the sky did clear up briefly so we could observe casually for a while and saw a few meteors before the clouds returned. Then we called it quits and came back home.
