                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J. Barentine
 Opened around 19:00 to ventilate under mostly clear skies and light
winds. Clouds rolled in from the west around 20:00 and were intermittent
until about 22:00 when the sky became almost totally clear again.  Seeing
was generally very good, only briefly popping up above an arcsecond and
usually in the 0.85-0.95" range.
 2nd Half Observing Specialist: N.C. Hastings
   Second half started smoothly again. No problems encountered, decent
seeing and clear skies. A few random cirrus clouds from time to time was
all.
