              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
During afternoon checkout I found that the blue side of the DIS vacuum pump was off and turned it back on.  It didn't have any more problems the rest of the night. CSS shows it was off from about 9am-5:30pm.
The night started out nice but became humid and cloudy after 22:00.  I was worried we would have to close but the humidity never reached 90% and we were able to stay open all night, albeit, with horrible seeing.
I did not hear the clunking from the left dorm door today.
