              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
First half started with thin clouds and good seeing, that turned to medium clouds and poor seeing, but observations continued through the clouds.  Second half had some thicker clouds so there was some idle time waiting for thinner patches - although we were open the whole time, I estimated how much of the weather was too soupy to be usable.
