              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
DIS ICC was not connected at checkout (could not ping).  IT got it working in short order for us tonight.
Clouds formed over us around 18:45.  We finished the 1st program but then closed after that finished as the clouds were too thick to observe at this point.  We never re-opened for the remainder of the night.
