              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
Snowing in the afternoon, and that set the feel for the whole night.  We had heavy clouds on and off all night, and bad seeing whenever we could get on sky.  We delayed opening to start, and only got on for a few hours before the clouds got hopeless and threatening.  We eventually opened again, and managed to close at twilight when humidity started getting bad.
