              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Night started out mostly clear with the threat of a fast-moving system coming from the west.  The system caused some clouds, but it fell apart around 0100, yielding clear skies.
Failure of DIS slitviewer at about 04:22, causing cancellation of UW05 program.
