Weather Report for December 28, 2011

Thin cirrus covered a large portion of the sky at sunset, especially to the south. Fortunately, the heavier clouds stayed to the south and the sky slowly clear during the night. Spectropolarimetry was not slowed at all and after midnight, the sky was photometric. The seeing was better than during the previous night, but it was still not great (1.5-2.5 arcsec).
