Another titanic struggle with thick cirrus had to be waged tonight.
The clouds were even worse than last night and only allowed spectropolarimetry
of about a half dozen blazars. Some of these measurements will
have relatively low S/N. Seeing was between 1.5 and 2 arcsec, but seeing
is the least of my worries during this campaign. Plenty of clouds are expected to
move through the area until the end of the campaign and then a storm
with a chance of actual rain is expected.
