              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
High clouds in the afternoon cleared by sunset, then returned for the middle of the night, and cleared again before dawn.  Seeing was moderate at the start of the night and good for second half.  Two targeted JHU programs combined with obseerver training for a group of JHU students.
ARCSAT had another clock problem, with a constellation of other problems that might have been caused by the clock problem or might have been independent.  Jack helped us sort them out.  The 3.5m and instruments all behaved nicely.
