              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Clear initially, then thin to medium clouds started moving in mid-evening.
 Seeing was moderate at first but worsened over the course of the night.
APOLLO had trouble again with its power supply, but this time a spare was
ready to swap in - only the seeing and the clouds remained a problem.
