              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
The night started off clear but with elevated humidity, which fell off, and then came back again after 01:00 as the clouds started getting worse.
We had one problem with TUI 3.1.3 on macos 14.1.1 which required clicking on buttons repeatedly in order to get them to respond. The TUI 3.1.4 beta version seems to work, otherwise, downgrading to at least TUI 3.1.0 is a temporary fix.
We closed up a little after 04:00 when it got completely overcast, in addition to the higher humidity and some radar coming our way from the south. We didn't reopen due to the radar nearby.
