              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
A clear night! Seeing was moderate given the north wind but we were able to stay open all night without issue. Since Ben has been testing the generator, I've been having to reset the mirror covers, which I think will happen for several more days. I focused kcam on the center position and it was closer to 1150 tonight (1200 last night) but it was still a bit viggly.
No problems tonight.
