August 11-20 Meteors

The Perseids peaked on the night of August 13 UT. Though the monsoon was still cranking and clouds were aplenty, 36 PER were detectedby the SALSA3 camera system.

Visual reports to the IMO show a peak ZHR of ~68. This is the true rate of the shower after correcting for the effects of the Moon-lit sky and the height of the radiant. Since 2007 the peak ZHR of the PERZ have ranged from 58 to as high as 180. 2014’s ZHR of 68 is the 2nd lowest of the past 8 years.
