              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
There was a miscommunication between the UC people, and the first few hours of the night were unused.  I finally got ahold of Sean, and we got the night rolling.
Seeing was variable, and some clouds started rolling in a little before midnight.  We pushed through it, even when they got a bit thick. Radar returns stayed south of us.  We closed a bit early because the clouds were too thick to get anything useful, however the time was still used for taking cals.  So I did not count this as time lost to weather.
