              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out clear with subarcsecond seeing but clouds started rolling in during B half. They had radar and, given that we couldn't even find a star to focus on and things were only expected to get worse, I called it at 6:00.
arcsat ACP crashed and broke the link to chrome. Restarting ACP did the trick. Then we had library issues and I needed to do a restart, which solved the problem.
