              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Holy cow, we had a good weather night!  I know, I'm as surprised as you are!  We were told it would be rainy and cloudy but it all stayed to the south of us and, not only were there hardly any clouds, but we had *AMAZING* seeing all night!  I wish we had been doing science given such great skies but lots of important engineering was done.
I accidentally left ARCTIC parked at rotation 270 last night and someone manually pushed it to 0 (moving through 270 so it was really at 360).  This caused the rotator pin to become unplugged and I got to learn how to connect it and learn behavior of an over-rotated rotator.
An ARCTIC instrument block was conducted in LL mode.
Shack-Hartman was run and we collimated the primary mirror.
A pointing model was run and there were only slight variations found.
A detailed email on the tasks was sent out.
No problems tonight.
