There were scattered, very thin cirrus clouds during the first hour of the night. The sky was clear for the rest of a very warm night on Mt. Bigelow and the seeing was good (1.2-1.5 arcsec). It was a very productive night of observing.
As a special bonus tonight, my very good friend Prachaks from Bangkok, Thailand, who I went to college with and have
not seen in over 20 years, and his wife, Mae, joined me at the telescope. They were
so impressed by the blazar monitoring that they went to bed before 2200 local
time. I blame their jet lag since observing is always exciting.
