              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
We had 1-micron dust counts up over 100,000, and when they finally came down it was completely overcast. There was no chance of doing any of the high priority on-sky engineering tasks, but I did recover a few of the missing quarter schedules from 2023 and 2024, tested some scheduling scripts for Shane, and updated some pages on the new wiki.
DomeCam computer restarted due to Windows updates. I also had to restart the video-35m-p computer since the dome camera feeds wouldn't load multiple instances anymore.
