The MC3 camera image has been down since 12:10 Fri 08dec2023 PST. There was nothing wrong with the camera, it just needed a restart of the h1cam12 server process on h1digivideo1. I killed the process and let monit restart a new one.

SHIFT SUMMARY: Just got back into Observing at 07:59UTC after relocking. Two locklosses during my shift, but both were quick to recover from. SEI_CONF is back to WINDY since USEISM is down.

00:58 Manually aligned green arms, and then started an Initial Alignment
01:21 Initial Alignment completed, relocking
- Watched ISC_LOCK log, ADS, and saturation overview screen closely between LOWNOISE_COIL_DRIVERS and LOWNOISE_LENGTH_CONTROL in case we lost lock during TRANSITION_FROM_ETMX, but we were fine

04:10 Changed SEI_CONF to WINDY due to lowering useism
- Went into the SEI_ENV code beforehand and swapped the SEI_CONF nominal states back to WINDY and EARTH_QUAKE from USEISM and USEISM_EARTHQUAKE(see 74727).

Lockloss 12/11 @ 06:46UTC due to sudden nearby ground motion
Observing at 160Mpc and have been Locked for 2 hours. Relocking after the lockloss (74725) went quickly, and ITMY5/6 are still damping well with Ryan C's new gain settings(74721)!
04:10UTC Secondary microseism is now consistantly below 0.8 um/s(ndscope), so I just went into the SEI_ENV code and swapped the SEI_CONF nominal states back to WINDY and EARTH_QUAKE from USEISM and USEISM_EARTHQUAKE(screenshot of change). I then changed SEI_CONF to WINDY.
Lockloss 12/11 00:47UTC for unknown reasons. EX saturation right before lockloss, and the light on the MC_REFL camera got much brighter than I had ever noticed before.

SHIFT SUMMARY: Quiet day, locked for 17:30 as of 0:00UTC.
I've finally found some settings that seem to work nicely for ITMY modes5/6, FM6+FM7+FM10 G= +0.02. They're trending down on broad, and narrow monitor filters, and on DTT. Tagging SUS

SHIFT SUMMARY: Currently Observing and have been Locked for 1.5hours. One lockloss during shift while I was running a Simulines measurement, so not sure if that could have/did cause it?
I have just left the ITMY Mode5 gain as 0 since it seemed like whenever I tried to change it, it would cause mode 5 to jump up and would take hours to get back to where it was before I turned on the gain. Mode 5 slope after changing gain from 0 -> -0.01 seemed to stay the same as well, and it seems like it takes a few hours after relocking for mode5 to start coming down.

- I manually took us state-by-state between LOWNOISE_ASC and TURN_ON_CALIBRATION_LINES due to TRANSITION_FROM_ETMX causing multiple locklosses for Ryan C earlier in the day (74704, 74703).

Lockloss 12/10 @ 04:45UTC while running Simulines calibration measurement
06:33UTC Observing
Locked for 3.5hours and Observing at 156Mpc. Relocking at the start of my shift went fine, and the ITMY5/6 violins are starting to all slowly decrease. Since Ryan didn't get to run a calibration measurement earlier today and LLO is down, I will now be starting the measurements since we've been up for 3.5 hours.

QUICK SUMMARY:
Detector is currently relocking and at ACQUIRE_DRMI_1F. Hopefully the Iceland earthquakes are done for today!
00:46UTC Back Observing
I used most of todays commissioning time for shaking and laser vibrometry to inform plans for the break. I replaced the MC3 camera over the viewport I had been using but couldnt get it to work. We will have to revisit it on a Tuesday.
The MC3 camera was brought back by Dave restarting the camera's server. alog74734
Also Verbals just announced an incoming 6.1 earthquake from Tonga, so I will attempt to get us back up but we might lose lock on the way up due to the earthquake.
