              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Night started out with multiple computer failures that took out many subsystems. One by one staff managed to get them back up, and we were on sky not too many minutes after sunset.  Skies were mostly clear, with occasional high haze. Seeing was average. All programs got their full times.
