              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
We had thick clouds for much of the night.  We were able to push through for most of it, after the radar returns cleared, but we did have some issues with echelle and Apollo.  When the clouds were clear, the seeing was pretty good.
