              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Clouds with some rain around 21:30.  Clearing around 23:00 but we had nearby radar returns just off to the west of us and the flow was in our direction so I opted to stay closed until the threats passed.
Clouds finally moved out around 03:00 and we managed to open for the remainder of the night.
