              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We battled high clouds all night, ranging from thin to medium.  APOLLO was not able to get signal and handed over a little early.  Other programs struggled but generally took data for their full time range.  Everything worked well except the sky.
