              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started mostly clear but with some wind.  We were able to open and have good skies for the first program but were plagued by clouds on the second program.  Finally, the humidity hit us after dancing around the limit for hours.  We closed during switch over to UW01 and remained closed for 72min until the humidity dipped below 80%.  We were able to stay open the rest of the morning.
AP01 ceded their time to UW01 in the morning.
I parked the dome south to try and melt and remaining snow on the roof.
No problems tonight.
