• 1820 Out of Observing, SQZ lost lock
• 1823 Observing
• 1930 Marc, Fil to MY
• 1957 Marc, Fil back
• 2150 Out of Observing to start calibration

Future Operators: If the squeezer drops and will not relock on its own, bring the SQZ_CLF_LR node to DOWN and then once that state has complete, bring it back to LOCKED. If this doesn't work after a few attempts, then it might be another issue.
