                 ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Noel Camron Hastings
     Opened the dome at 17:00 MST to allow a couple hours to cool. No
problems encountered. It does seem that the software interface to control
the eyelids is not working. I was told Dave Woods changed the way in
which it works, so perhaps the bit numbers I am using are no longer
valid. No observing trouble encountered.
 Observing Specialist, 2nd Shift: Russet McMillan
Second half went very smoothly.  There were varying amounts of light
cirrus most of the time, clearing toward dawn.  The seeing was better
than 0.7 arcsec whenever it was checked on a bright star.
