                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Jack Dembicky & Russet McMillan
 Observing Specialist, 2nd Shift: Russet McMillan
 Low clouds cleared off around sunset, and the dewpoint dropped faster
 than the temperature.  Thanks to extra work by Jon Davis in clearing
 ice off the roof, we were able to open at sunset.  The night remained
 beautifully clear, with good seeing during first half and several
 hours of variable seeing during second half.  Although it wasn't a
 science target, Mercury was astonishingly bright and relatively far
 up the sky at the beginning of morning twilight.
 The night was very successful.  The instrument block for the new
 Acousto-optic IMaging Spectrometer was finished quickly and smoothly,
 and the team was ready for science by 20:00.  All went well until
 Saturn set and we closed just before twilight.
