              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
Except for a short period of semi-thick clouds, the night was clear with beautiful seeing.  Very productive with no problems.
The tspec aux tank was reading warm, and has been for the past week or so.  I topped off the aux tank this afternoon, but it didn't take much and didn't change the behavior.  So all seems fine despite the reading.
