SHIFT SUMMARY:
- EX saturation @ 16:46
- Lockloss @ 17:46, cause unknown
- ALS caught on relocking, but PRC1 would not converge on IR, spot was also poor on AS AIR, so running an IA
- Back to NLN @ 19:04/OBSERVE @ 19:08
- EX saturation @ 20:06/20:18/22:50
LOG:
No log for this shift.
Lockloss from earlier this morning, but following an initial alignment, H1 is back in observing as of 19:08 UTC. Microseism is continuing its downward trend, violins looking good.

SHIFT SUMMARY: Quiet evening, Observing and we have now been Locked for over 12hours. Wind has gone up a bit but is still pretty low. Microseism is slowly decreasing, and violins are doing well. SEI_CONF is still in USEISM, and SEI_ENV is still set to CALM
LOG:
00:00UTC Detector Observing and Locked for over 4 hours
- SEI_CONF in USEISM and SEI_ENV in CALM
Commenting on my shift end from yesterday evening - at 07:39UTC 11/26 we had a DCPD saturation (plus an EX saturation) that did not cause us to lose lock. It doesn't happen often that we get DCPD saturations without a lockloss so just mentioning it!
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:

- CDS ok/PSL DM 102 still not getting readback
Dense freezing fog through the city and on site today...

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.
