                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Barentine
 Opened shortly after 17:00 under clear skies and variable winds, at time
bumping up toward the closure condition.  Winds kept up through the first
half.  Seeing varied between 0.80 and 1.00"
 2nd Half Observing Specialist: R.McMillan
 Second half was clear with seeing that was sometimes excellent but
 never perfectly stable (0.7-1.5 arcsec).  Everything worked
 perfectly.
