              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
Opened at 19:54, but the clouds built up too quickly to see any targets.
We did not focus before closing. I noted the open and close times in the
log, but these only correspond to the dome state. After trying to get on
sky at 00:20, SPICAM was freezing on image readout. Restarting nubs,
instrument, and ICC did not work, until I employed an order of operations
of these actions that apparently hit the spot. This took an hour of
questionable sky time, unfortunately. Once it was fixed however, there was
no science taken due to clouds, so I also logged all this time to weather,
thinking that sky conditions were the same regardless of hardware issues.
No science taken all night. Called it at 04:50.
