Weather Report for November 26, 2016

The sky was nearly completely clear at the start of the night, but after the first couple of hours, cirrus clouds began moving in from the southwest. Observations continued all night long through various amounts of cirrus and over 20 blazars were observed. Except for the first half a dozen targets at the beginning of the night, photometry was hopeless. The seeing ranged from around 1.3 arcsec to 3 arcsec. Fortunately, the periods of very poor seeing were not lengthy.

This may be the last night of observations for several days as a major winter storm is supposed to bear down on Arizona starting tomorrow.
