                 ------------- ACTIVITY LOG --------------
 Observing Specialist: Russet McMillan
 We opened in mid-twilight when the afternoon rain had cleared away;
 occasional clouds troubled us, but improved as the night went on.
 The seeing started out quite good (0.8 arcsec), but soon became
 variable with spikes greater than 2 arcsec.  A lot of the seeing
 behavior looked like windshake on the telescope, but the wind was
 only 15 mph.  Second half was mostly clear, but also plagued by the
 unstable seeing.  Aside from the weather, everything worked
 perfectly.  There were no guider failures.

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