Weather Report for October 25, 2011

This night was remarkably poor given the great observing conditions exploited only 24 hours earlier. Clouds forced several dome closings and wiped out nearly half of the night. Even during the clearer periods, observations were often slowed by clouds. The seeing was reasonable during the useful parts of the night and often around 1 arcsec. Little photometry was attempted. Although 10 blazars were successfully observed for polarization, several measurements will not have the extremely high signal-to-noise ratios typically achieved by the monitoring program.
