              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Start of the night NICFPS required an expose init to get it working right. Evening started out partly cloudy, then it cleared around sunset.  By midnight, high haze was being observed on the IR cam, but humidity was still within limits. Clouds began to form by 00:30 and by 00:40 the humidity had passed safe limits, so we closed. The humidty started to track down, and we opened again at 04:10.  We stayed open until dawn.
