              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We fought clouds all night long, never closed but the clouds did not help observations at all, especially 2nd half.
Nothing useful after 02:50, although we stayed open and hoped.  We finally threw in the towel at 04:10 with orographic clouds completely clouding us out.
