              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland

Waited to open as truss cals were being taken at sunset. Opened at 19:35. Beautiful weather all night. 

Dome/roof cam computer restarted on their own at checkout. All sky camera was also frozen, and computer was logged out. Restarted/logged back into everything and all was well. 

Arctic LL quad fully recovered by b-half! Yay!

Users in a-half and b-half had issues of being kicked off TUI, though I stayed connected on ObsA the whole time.

No problems tonight :)
