              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We managed to get about 2 hrs of data thru lots of clouds during the first half.  The mirror/dome was warm so we pushed the humidity limits as long as I could.  2nd half the humidity increased with fog at the end of the night.  We called it at 04:50 with little hope for improvement.
DIS red cryotiger, ion pump, and alerts turned off @05:10.
