Weather Report for December 11, 2015

In a reversal of the previous night, observing was much better in the first half of the night than after midnight, when thicker cirrus moved over the observatory in advance of a major winter storm that is expected to hit tomorrow night. Despite the generally sloppy skies during the night, nearly 20 blazars were observed, though many will not have a flux measurement to accompany the spectropolarimetry. The seeing varied between 1.5 and 2 arcsec.
