              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Somehow we were open most of the night! But we had high dust the whole night, hovering just under the closure limit. Seeing was pretty good until we had to close around 03:30 am due to approaching radar and clouds that were getting too thick to punch through. The UW02 class did a great job with their first night on sky!
No problems tonight.
