                 ------------- ACTIVITY LOG --------------
 Observing Specialist: Russet McMillan
 The dome was opened slightly late for cooling due to some extra
 checkout needs of the visiting instrument, but we were able to focus
 soon after twilight and obtain an instrument block -- the first one
 measured for this instrument despite its previous visit.  Everything
 went very smoothly after that, with telescope, guider, and instrument
 all behaving well.  Skies were clear all night and seeing was
 generally moderate (1.2-1.6 arcsec), with a few short periods of
 subarcsecond seeing.
          --------------- OBSERVER COMMENTS ----------------
R.Wurtz (DD03):
Seeing was okay.  Dome was too chilly.  No problems.  I don't think we
had a single problem.  We pointed just .  Clear all night.  A
little windy.  Happy that instrument block is done.  I hope tomorrow
night's as good.
