                 ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 The telescope was open for cooling before sunset, but approaching
 heavy clouds caused me to close just as the sun went down.  We
 re-opened as twilight officially ended and got some good data on
 Venus while the solar-driven clouds dissipated.  Later, orographic
 clouds caused some difficulty, but we never had to re-close.
 Pointing was excellent, and everything worked well.

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