(meteorobs) Report October 20/21 (Oregon)
I planned on doing two hours this morning, but woke up to find the sky 1/2-cloudy at 3:45am (10:45 UT). I waited a bit, and the sky cleared quickly, leaving behind some moisture-laden haze. I got an hour of Teff in, although I did deal with some clouds in the latter part of the viewing session.
Orionids were about as active as during my last session on Oct. 18/19, with 17 seen. No fireballs, but a few nice bright meteors.
