              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
ecamera was hung (error stated it was taking another exposure?) at checkout.  I tried to restart both ecamera and ecam, but this didn't work.  I had to power cycle the camera, which fixed the problem.
Sky started clearing around 22:00 but we still had nearby rain showers just off to our west that prevented us from opening until they moved a little farther away.
Opened around 22:50, closed an hour later as a system moved by just to our west.
We re-opened at 01:05 and stayed open the remainder of the night, despite humidity for part of the 2nd half.
