              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started cloudy.  Radar returns began to pop up near us around sunset. We held off opening until 18:30.  Clouds were somewhat thick, but we were able to get data. Around 19:45 clouds thickened more. The clouds began to thin around 23:00. They stayed thin until dawn.  All programs got their full times.
Dcam showed signs of shutter issues (vertical streaks), as well as static on several frames, at times bad enough that we lost guiding.
