Weather Report for March 7, 2011

Fairly thick cirrus covering most of the sky at the start of the night. Useful polarization observations of 7 bright targets were obtained before midnight during periods when the cirrus thinned out. At about midnight, the cloud cover thickened and the wind strengthened. By 0100 local time, the wind reached a point (40mph+) when the dome had to remain closed. The overcast continued and the wind worsened (gusts of 50mph+ were common) through the rest of the night. The seeing was quite acceptable, at around 1.5 arcsec, despite the poor sky conditions during the early portion of night. As with the previous night, the sunset was fantastic. Hopefully, we'll have less drama from the weather and more productive blazar monitoring tomorrow.
