              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
The night started out clear but with increasing clouds.  Seeing was bad, but got better as the night progressed.  We almost got clouded out around midnight, but then it unexpected cleared.  The rest of the night was mostly clear with an occasional cloud bank. All programs got their full times.
