A mostly clear night with over 15 blazars observed. A thick band of cirrus in the west after sunset prevented a couple of objects from being observed before they set. After that, only thin cirrus soiled the sky and there were a few periods during the first half of the night when the entire sky was clear. The seeing was good all night, ranging from 1-1.5 arcsec.
There was difficulty locating a source for satellite weather images tonight,
resulting in the different style of image shown below.
