From 7-9h UT, lots of Perseids seen; at times, one or two were seen every
minute.  This is the best Perseid shower I've seen in 20 years as an observer.
Remarkably, also from 7-9h UT, I witnessed an awesome display of Aurora.
From my location 65km east of Cleveland, Ohio, USA (81.0W, 41.5N), aurora
extended through 180 degrees of azimuth, centered on north and up to 20
degrees past zenith.  Individual curtains were up to 80 degrees in length.
The brightness at times made it difficult to see 2nd magnitude stars.  Many
Perseids were seen against the aurora.  In my experience, only the March, 1989
and March 1990 displays exceeded this one.  The only downside of all this is
that not much VSOing was done during this time.  A very memorable night!

Instrument: 50.5cm f/5 L (and naked eye too)
