              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started out partly cloudy.  High humidity kicked in shortly after sunset, forcing us to close until 23:26.  After that, not much data was collected due to the clouds passing through (IR and even thin clouds don't mix).
The humidity stayed just under closure limits until 03:30 then rising humidity and a storm to the north of us forced a close.  We remained closed. Scope was left at 104,84 for the apollo team.
