              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland
I didn't trust the clouds not to rain at the beginning of the night, so I stayed closed for a little while just to be sure. Opened just after 9pm.
Closed due to humidity just before 1am. Humidity stayed up and we didn't get to open again. We gave up around 5am.
No problems tonight.
