              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
So apparently the ARCTIC shutter is not happy at -10C, when I did my checkout.  Unfortunately I didn't notice (since we only do biases) and since the temp had warmed up at the start of 2nd half to around -4C I forgot to take a look.  The observer noticed vertical streaks on her bright stars let me to an open shutter.  Resetting the shutter control box on ARCTIC quickly fixed the issue.  I recommended re-taking her darks (and anything that would be affected with a stuck open shutter).
No other problems tonight.
