                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 SNOW!!!  OK, we aren't supposed to be happy about cloudy weather but we
 really needed the precip up here.  By 20:30 we had about an inch
 accumulation (and still falling).  I called the night since this was a
 really heavy and wet snow and we had accumulation on the enclosure.
 We got about 2 inches of wet stuff.  Roof heaters and snow program ran
 all night, roof heaters left on.
