              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland
Cals were being taking until 19:15.
Restated dataq at 18:50. Again at 19:40. Again at 21:20.
High winds caused us to close at 21:50. Wind persisted through the night with gusts hovering around 40mph. Around 3am radar returns popped up  nearby, but no precip on site.
ObsA TUI froze at 01:50ish and took a long time to reconnect. My laptop also would not connect in a reasonable amount of time. It took a full 2-3 minutes to connect/authorize my login. It froze for OU02 as well. Afterwards, there was a lag between my laptop and ObsA (laptop got messages first, obsA about 10 seconds later).
Dome parked facing west due to consistent 45mph winds from the southeast.
Called it a night around 4am.
