              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started with scattered showers that turned to snow. No accumulation.  After that, there were numerous radar returns in the area, we waited until they passed. We opened at 21:15, though clouds continued to be a problem for some time afterwards. It cleared around 23:00. It stayed clear and dry with decent seeing for the rest of the night.
