Weather Report for June 1, 2011

A very messy end to observing campaign 28. Cirrus of varying thicknesses covered the entire sky all night long. Despite this, spectropolarimetry of nearly a dozen blazars was accomplished, but generally the results will not have the very high signal-to-noise ratios that are typically achieved for this program. Photometry of only one object could be obtained and only because BL Lac and its comparison star can be placed in the observing slit together. Seeing was 1.5-2.0 arcsec. The show switches over to Mt. Bigelow for the next campaign during the last week of June.
