The first three hours of the night were a total loss because of clouds.
After opening the dome, operations were slowed until around midnight by occasional clouds that would pass through fairly quickly. The second half of the night was generally clear and some spectrophotometry was done to go along with the spectropolarimetry. The seeing started off at 1-1.5 arcsec, but as the sky became clearer, it degraded to around 2 arcsec or a little worse. Over a dozen blazars were observed during the partial night.
