              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We were plagued by clouds all night.  Thankfully, none of them held rain.  They did, however, want to stay and hang around.  We had an orographic cloud stay with us the entire night and killed any hope of observing in the East.
I think I saw an issue with the rotator tonight but I'm not sure.  After I set inst dis and slewed to a focus star, the rotator did not move.  I had not set a value for rotation, so that might have been it.  There were no problems when I slewed to park with a /rota /rotty command.
