                 ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st & 2nd Shift: Jack Dembicky
Clouds, high humidity and lt. snow prevented opening tonight.  I started
the snow program (just as a precaution to prevent snow accumulation)
around 21:00 tonight.
I turned the roof heaters on at 04:00 and the snow program was stopped at
this time also.
