              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
We started out with some afternoon rain. Opened late due to threat of rain. It passed, as we opened around 20:30. Seeing was bad. We had to close again around 23:20 due to possible rain clouds coming up on us. They passed by 01:00, and we opened again. We stayed open all night, seeing improved somewhat.
