              ------------- ACTIVITY LOG --------------
Observing Specialist: M.Croom
Started the night with sub-arc second seeing that degraded as the winds picked up, and then improved again nearing dawn. The skies remained clear and we were able to stay open all night.
The onsite observers seemed to have a very productive and instructive visit thus far, and were an absolute pleasure to work with.
The KOSMOS remote user had the slitview window freeze. Quitting and restarting TUI resolved the issue (user was running TUI 3.1.2 with macOS 11.7.10).
No other issues tonight.
