                ------------- ACTIVITY LOG --------------
Observing Specialist: G.Saurage
Clear skies at sunset. Clouds began rolling in around 10:45, closed at
11:20. The clouds were forming just NW of us in the basin making the few
holes that popped up untrustworthy. We reopened at 2:20. Variable seeing
and fluctuating humidity the rest of the night.
