Weather Report for January 25, 2012

The storm system that prevented observations on the previous night did not move away from Arizona as fast as hoped and the first two hours of the night were lost to high humidity. Unfortunately, this delay prevented observations of early evening objects as they set by the time the dome could be opened. After that, conditions were clear with reasonable seeing (1.4-1.8 arcsec). Light cirrus showed up a few hours before the end of the night, complicating some attempts at photometry. The cirrus did not slow spectropolarimetry.
