                 ------------- ACTIVITY LOG --------------
 Observing Specialist: Russet McMillan
 A productive night despite some thin clouds at the beginning and end
 and distraction in the form of a film crew on-site.  Seeing was
 moderate (0.9 to 1.5 arcsec, worse for a few high-airmass targets),
 and the sky was clear during the middle portion of the night.
 Everything worked well, including our first real observing test of
 dark subtraction for faint objects with the echelle slitviewer.  The
 only problem was a recurrence of the troublesome SPIcam ramp at the
 beginning of the night, which wasn't entirely cleared up by the time
 observations started.

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