Finally, after almost a week, a full night of observing! So far, the only
other complete night was the first night of the campaign.
The sky was photometric with good seeing (0.9-1.5 arcsec) until about
0130 local time, when thin scattered cirrus from the tail of another
weather front to the north came over the observatory site.
The wind rose during the night to 20-30 mph, but stayed safely below
the limit for observing.
The cirrus did not significantly slow observations and cleared off, leaving
photometric conditions during the last couple hours of the night.
