                  ------------- ACTIVITY LOG --------------
 1st half Observing Specialist: B.Ketzeback
 Humidity was over the closure limit all of first half. The rain sensor
 went off at 2230 due to light snow flurries.
 2nd half Observing Specialist: R.McMillan
 Freezing fog (or would that be floating frost?) attempting to turn
 into snow but not quite making it.  3-5 inches my aunt's left elbow...
 If smoke + fog = smog, does frost + fog = frog?

   used is north=0 degrees, east=90 degrees.  The dust count is
   particles > 1u per 0.1 cubic feet.
   Note: The weather tower dust counter is out of commision
