                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Clouds started the evening, then the humidity went over the limits.  This
 kept us closed the first half.  Around midnight it was snowing/raining.
 We gave up around 4AM due to the clouds and humidity.  We had about an
 inch of snow on the ground when I left this morning.  Roof heaters were
 left on, air temps were just above freezing.

     Note: the wind was coming from the azimuth listed.  The convention
     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
     Note: The Tower Dust counter appears to be down at this time
