Weather Report for March 5, 2013

Scattered light cirrus greeted the start of Campaign 48 at the Bok Telescope on Kitt Peak, AZ. The cirrus generally became more of a problem after midnight, but it was difficult to obtain reliable photometry throughout the night. Polarimetry was slowed by the clouds only in the last 1-2 hours of the night and over a dozen blazars were successfully observed. The seeing was between 1.4 and 2 arcsec.
