                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 At sunset, there were multiple storms surrounding the observatory at
 a distance of 50-100 miles.  At least one was heading in our
 direction, but slowly.  I decided to open, but kept a close eye on
 the weather.
 The storm heading our way dissipated with the loss of sunlight, but
 after 21:00 the thin clouds that pestered us began to thicken.  At
 the same time there was a wave of cold air and gusty winds, so we
 closed just before the humidity and wind went over the limit.
 And stayed that way.  With some rain for good measure.

     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
