              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
Tspec had corrupted images at the beginning of the night. I changed the
NFS to 1 from 8, the darks cleared after the next exposure. Going back to
NFS=8, they appeared disturbed again. See test darks in checkout
directory.
We were closed all night for snow, running the snow program after a
consistent snowfall began shortly after 21:00. The heaters were left off
because it was too cold, and both telescopes were parked in the south for
maximum exposure.
Completed fills and went to bed at 04:00. See snow report email.
