              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Night started out mostly clear and warmer than its been.  We were able to get on sky out the door, but clouds began coming in around 22:00.
Side note: Tspec giving corrupted images on checkout.
Clouds did not force a close, and it cleared up by 01:30. Rest of the night we had intermittent clouds, but stayed open.
