              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started partly cloudy. Arctic was having troubles with its power supply, so we moved it onto the old DIS blue PS. Seemed to work. Evening started with high thickening clouds, but good seeing. Clouds kept getting thicker by midnight could only see the moon. By 02:00 even the moon was getting hard to see. Rain started popping up on radar, so we closed. Observer called it quits around 03:00. We did not open again.
