STATE of H1: Corrective Maintenance
OUTGOING OPERATOR: Tony
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 22mph Gusts, 15mph 3min avg
    Primary useism: 0.04 μm/s
    Secondary useism: 0.16 μm/s
QUICK SUMMARY:

IFO is DOWN for MAINTENANCE

With full brevity, something is broken and we don't know why. You can use this alog as a glossary for ideas and tests that our experts have had today:

Much like yesterday, guesses involved the IMC, so Sheila and Ryan went into the PSL with no immediate culprits. IFO was extremely glitchy while observing so we made the call not to try locking at the risk of damaging. If comissioners think of anything to test, they will let me know.

Relevant alogs from throughout the day:

• Alog 86865 - Tony's Summary OPS alog.
• Alog 86860 - IMC Degradation Pre/Post Outage
• Alog 86861 - IMC WFs Comparison Pre/Post Outage
• Alog 86857 - Corner Station Dust Monitor Pump High Dust
• Alog 86855 - ISS Second Loop Glitch Investigation
• Alog 86852 - IMC OLG and Demod Phase Check
• Alog 86848 - Extreme glitching correlated with IMC WFs

Alogs are still being written as it's been a long and busy day. I will add more throughout the shift.
