A very windy start to the night with gusts over 30 mph commonplace before
midnight. The wind calmed to 5-10 mph during the second half of the night.
skies were photometric all night long, but a huge drop in temperature during
the night resulted in very poor seeing. The seeing started out at a little
under 2 arcsec and progressively worsened. By the end of the night, seeing
of 4-5 arcsec was the best that could be coaxed out of a primary mirror that
was at least 15 deg F warmer than the freezing temperatures that were reached
by morning twilight.
