              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started out partly cloudy and clearing for the first half. Winds were calm and seeing was very good.
The clear skies persisted past midnight, at which point clouds started coming in.  By 02:30 the observer was getting no data, and with some precip showing on the radar headed our way, we closed the dome.  With little hope of improving conditions, the observer logged off by 03:00.
