                   ------------- ACTIVITY LOG --------------
 1st half Observing Specialist: B.Ketzeback
 First half started off quite well with clear skies and subarcsecond seeing.
 Within an hour a band of light cirrus passed through then quickly cleared.
 Towards the end of the first half a thicker system moved in causing poor
 seeing (greater than 2 arcseonds) and variable cloud cover. We were able
 however to remain open and use all of first half as there was no real danger
 of moisture in the area. Everything performed wonderfully.
 2nd half Observing Specialist: R.McMillan
 Second half had variable clouds and poor seeing (1.5-2 arcsec), but
 otherwise everything was fine.

      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: Tower dust counter is down. No readings were available.
