                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan, G.Saurage
 Nearby rain kept us closed at sunset, and clouds stuck around a
 while longer.  We were able to open shortly after midnight despite
 borderline winds; of course, our seeing was pretty poor.  The sky
 was nearly clear for a bit, giving way to patchy orographic clouds.
 I closed when we had a combination of medium clouds and some radar
 returns in the area, but those turned out to be noise and we soon
 reopened.  Near twilight the humidity got up to the limit, but with
 fans off the telescope stayed warm enough to be safe.

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