Weather Report for March 5, 2011

A photometric night until the last 2 hours of the night when thin cirrus rolled in from the west. This prevented photometry of the last targets of the night, but had little impact on the spectropolarimetry. The seeing varied from 1.2 to 2.5 arcsec, but much poorer seeing (3-4 arcsec) was endured during the last 2 hour of the night. Like the previous night, this was a very productive observing session.
