                ------------- ACTIVITY LOG --------------
 Observing Specialist: W.Ketzeback
 Looked like rain just an hour before sunset but it moved out of the area
 by the time we were ready to focus. After focusing the guider the new
 shutter that was put in earlier today failed after about 30 exposures. The
 guider reamined useless for the remainder of the night. No other problems.

     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: The Tower Dust counter appears to be down at this time
