STATE of H1: Corrective Maintenance
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY: Quite a lot of environmental noise today, high microseism (it turned around after touching the 90th percentile and is decreasing), a wind storm with sustained 40+ mph winds, and a large earthquake. The main focus of commissioning today was SQZer and OMC. CDS_OVERVIEW shows lock loss alert is down, disconnected channels.

- 14:30 - 17:15 UTC I was able to lock PRMI fairly easily, though the spot looked pitched. Maximizing the power with PRM didn't seem to fix the beamspot much. I then tried DRMI which locked after a bit and I touched up PRM and SRM and the spot looked decent. It held for a good ~20 minutes before I lost it and wasn't able to relock it. Wind + microseism maybe? I stopped to let SQZer take over SRM and Oli take BS transfer functions.
- ~19:00 UTC Jim turned on CRS damping, and an OMC scan was started
- 20:00 UTC I recovered EndX
- 21:36 UTC EQ mode from a 6.6 from the New Caledonia/Fiji area
