              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started with local fog and snow showers on the radar.  Started running the snow program at about 18:00.  We remained closed throught the first program. Freezing rain and snow began around 00:00. Mostly snow by 04:00.
With no hope, we gave up at 05:00. No observing was done.
We had about 1.5" of snow.  3.5m catwalks and east walkways were shovelled. Scope was left pointing due south, after having run the snow program all night.
