                 ------------- ACTIVITY LOG --------------
 Observing Specialist: Russet McMillan
 A nice, mostly-clear night, with good to moderate seeing (except that
 the observers spent lots of time at >2 airmasses).  Even when the
 wind shifted to the east, there were no dire consequences to the
 dust, humidity, or seeing.
 We had a little trouble at the transition to second half when the
 eyelid wouldn't open for the echelle; that cost about 5 minutes.  A
 later difficulty when the remote observer's Mac crashed and hung up
 the MC, possibly due to slitviewer communications (does this sound
 familiar?) cost no time, since the echelle continued to expose during
 the hang and eventually read out normally.

  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.
