              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had waves of patchy clouds for much of the night except for a couple of hours in the middle.  First and second half programs did manage to observe through the clouds for the most part, so hopefully they will be able to get use out of their data.
