                  ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 A large storm to our southeast at sunset (in our radar blind spot)
 caused various problems because of its outflow even though the rain
 never got here.  We had a variety of clouds, seeing conditions, and
 dust and humidity levels, with the worst of everything during first
 half.  But we never had to close, and eventually the weather calmed
 down and became borderline photometric by morning.  The telescope
 and instruments performed very nicely.

      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.
