A beautifully clear night until the last hour or so when scattered thin cirrus came up from the south. Nearly 20 blazars observed. The seeing was 1.1-1.5 arcsec for most of the night and then around 2 arcsec near the end.
The forecast for the next several days is not promising as the low pressure
system off of the Baja California coast that hindered the program a few nights ago finally and very slowly
comes back toward Arizona.
