In Observing and now Locked for over 8 hours. Everything has been calm besides some EX saturations. ITMY modes 5 and 6 are behaving.

SHIFT SUMMARY:
- 17:37 - inc 5.6 EQ from Northern Mariana Islands
- Lockloss @ 17:46
- Relocking was still a bit tricky going through PRMI thrice before finally catching
- Back to NLN @ 19:49/OBSERVE @ 19:53 (only 4 minutes for ADS to converge!)
- EX saturations @ 19:56/21:00/23:48
- PI 31 ringups @ 19:57, successfully damped by guardian
Range has been on the lower side these past few locks, hovering between 140-150 Mpc.
LOG:
No log for this shift.
Following a lockloss after a 21 hour lock and struggling with high microseism trying to reacquire, H1 has finally made it back to low noise and observing (as of 19:53 UTC).
Sat Nov 25 10:03:57 2023 ALERT: Fill done (errors) in 3min 54sec
A quick fill which did not automatically stop because the TCs did not reach the trip temp of -100C. Outside temp was -4C at the time of fill, TC-A only reached -97C.
I manually stopped the fill after the TCs had flat-lined for about 30 seconds.
I have changed the trip temps to -90C
Lockloss @ 17:46, possible ASC ringup, SRC loops in particular.

QUICK SUMMARY:
- H1 locked for 26 hours
- Microseism still on the rise, violins also high (looks like guardian turned off settting for ETMX 9 last night, ringing up the mode)
- CDS ok/PSL DM 102 still not getting readback
Dense freezing fog through the city and on site today...

SHIFT SUMMARY: Observing and Locked for just over 18 hours. Quiet night overall. Violins are looking okay, microseism is still pretty high, SEI_CONF is still in USEISM, and SEI_ENV is still set to CALM. The VIOLIN_DAMPING and ISC_LOCK nodes have not been reloaded yet.

STATE of H1: Observing at 155Mpc
OUTGOING OPERATOR: Austin
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 11mph Gusts, 9mph 5min avg
Primary useism: 0.07 μm/s
Secondary useism: 0.36 μm/s
QUICK SUMMARY:
Observing and Locked for over 10hours now, everything looking good. Will keep a close eye on violin modes.
SEI_CONF is still in USEISM due to high microseism, and the SEI_ENV is CALM instead of WINDY.
As previously noted (74392), the control room hasn't been getting readings from the PSL 102 (anteroom) DustMon for dust counts, temperature, or humidity. This started around 19:30UTC on 11/21/23(ndscope), which would have been during the time that Jason and Ryan S were in the PSL enclosure. I had asked Ryan S to do the PSL Dust Monitor FAMIS check for me if there was time after the ReflCav adjustment. I am not sure if he ended up having time to test the dust monitor then, but if so, something might have gotten messed up while/after the check that may explain the readback issues.
Ryan S had not tested the dust monitors in the PSL so DustMon 102 not getting new dust/temp/humidity readings due to some other issue.

H1 is currently locked for 6 hours. ITMY mode 5 with Ryan C's new setting has been damping the mode well, but looks like it is starting to ring up mode 6? Seismic activity/wind is also low, but microseism is still near the 90th percentile. Range hovering around 155 Mpc.

Very quick fill, TC temps look good but discharge_press did not get very high.

QUICK SUMMARY:
- H1 in observing, current lock stands at 2:15 hours
- Ground motion has since calmed down from last nights EQ, but useism is still very high - almost in the 90th percentile, holding SEI CONF in USEISM until it goes down
- CDS ok/DM PSL 102 not getting any readback

SHIFT SUMMARY:
H1's been locked for about 20.75hrs. The range has been somewhat decent in the last hour.
Only other notable item is the Squeezer losing lock and dropping H1 out of OBSERVING at 0458utc & relocking 2min later.
Just adding a note, I forgot to mention for my summary last night:
Still on the To Do List:
