              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
TUI crashed during checkout for no apparent reason. The problem didn't reoccur, so no idea what that was about. I also had to reset the mirror covers, probably due to a power glitch during the day.
Some light cirrus started to move in beginning around 19:00. The clouds got slowly worse throughout A half and persisted until beginning to clear up after ~02:00.
No problems tonight.
