              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started wet and cloudy.  There was snow earlier in the day and some accumulation on the roof (~1 inch).  The clouds and fog cleared and we were able to open at 21:04.  However, Fog 2 -The Revenge occurred at 22:42 and we had to close again.  We were not able to reopen for the rest of the night.
There were two occurrences with azimuth motion errors tonight, one at az=98.6 and another at 99.4.
