              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had high clouds during first half, and also borderline winds.  As the wind shifted east and the target tracked west, I had to ask the observer to move away from the primary science target.  But we were able to keep observing on some secondary targets so the time wasn't really lost.
During second half the wind and clouds eased up, and everything was very peaceful.
