              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
The night started out very cloudy and very dusty.  The clouds cleared, but the dust stayed with us.  It was right around the closure limmits most of the night, although I stayed open.  The mirror probably needs to be checked for dust.
No other problems to report, and seeing was good most of the night.
