(meteorobs) Observations August 12 from Oregon

[Wes Stone]

I volunteered at a public star party on the night of August 11/12 (timed as 
usual to coincide with Saturday night rather than with the traditional 
Perseid peak). A gate counter estimated 160 people showed up, which is 
exceptional for this rural area with no astronomy club. The event was held 
on the grounds of the Fort Klamath Historical Museum  in Klamath County, OR. 
I did a couple of meteor talks and some telescopic view-sharing before 
settling down to meteor counting after midnight. Perseids were quite active, 
especially during my pre-twilight session which included a lot of faint 
activity. Aquarid and Kappa Cygnid radiants were also active, with the KCGs 
producing a couple of bright meteors early and late. I saw 175 Perseids and 
246 total meteors in 3.28 hours Teff.
