              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I had a rot1 error when switching to ARCTIC.  I reset the drive controller and that fixed the issue.
My TUI disconnected at around 10:11:00 UT.
Dataq did freeze and needed to be restarted.
No telescope issues tonight.
