              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
During checkout, NICFPS images were corrupted, fixed by an init.  ARCTIC images were corrupted (this seems to be a pattern lately), fixed by restarting the ICC program.
Patchy to thick clouds at sunset permitted me to get twilight flats with ARCTIC which can be paired with last night's standard star data.  I made two attemps to get a pointing model but didn't get more than a few stars before the clouds thickened up.  I checked DIS spectrograph focus, which did not need to be adjusted.
Later, we had heavy rain and a power outage which switched over to generator power at 23:18.
