The night was ruled by thick cirrus for most of the time, with relatively
clear conditions during about three hours in the first half of the night and
less than two hours at the end of the night. Progress was very slow from
about 2300 local time until just after 0300. In spite of the poor conditions,
a dozen blazars were measured for polarization. Little photometry
was done. As a consolation prize for putting up with a constant stream of
high clouds from the west, the seeing was better (1-1.5 arcsec) and more
stable than in previous nights this campaign.
