                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 High cloud cover all night until 5:30 this morning. There was an instance
 when the slitview software driver locked up and the dcamera/dcam software
 needed to be restarted. It was not immediately obvious to me however if we
 had lost the object due to cloud cover or another reason. The observer paused
 the science exposure until I fixed the problem. About 10 minutes of sky time
 was lost. The rest of the night went smoothly.
