                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Closed all night due to clouds, humidity, fog, rain, sleet, snow,
 grapple, and lightning.
 Enclosure roof heaters left on since we were right at freezing and I
 wanted to try to melt some of the ice from the sleet earlier.

     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
