STATE of H1: Observing at 158Mpc
OUTGOING OPERATOR: Corey
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 5mph Gusts, 2mph 3min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.23 μm/s
QUICK SUMMARY:

• We've been locked for almost 8 hours, 2ndard microseism has leveled out, low wind
• Low range coherence check for this lock

H1 will be thermalized right around the Sat Calibration time of 1930utc (1130am PDT).  L1 has been down due to a frontend crash/chassis swap this morning, so will jump on this down time to get the calibration run for H1.  Louis Dartez wanted operators to continue running the new/non-standard simulines measurement (noted below).

Measurement NOTES:

• Following instructions (link).....EXCEPT:  Again for simulines measurement, run this file per Louis D.'s request:
  • " gpstime;python /ligo/groups/cal/src/simulines/simulines/simuLines.py -i /ligo/groups/cal/H1/simulines_settings/newDARM_20231221/settings_h1_20241005_lowerPcal_higherPUM.ini;gpstime "
• H1 at NLN for for over ~3hrs
• Calibration_Monitor medm screenshot is attached
• 1930-2002  Out of Observing for CALIBRATION
• 1931 -  1936  Broadband measurement run
  • Measurement at:  /ligo/groups/cal/H1/measurements/PCALY2DARM_BB/
• 1936-2000   Simullines measurement
  • Before starting this measurement, Commissioners took H1 to No SQUEEZING, and then we started simulines
  • gps START time:   1417030617.990077
  • gps STOP time:  1417032042.257816
  • Files writtten to subfolders here:  /ligo/groups/cal/H1/measurements
• Let commissioners know when calibration was complete and they brough back squeezing
• Then ISC_LOCK was taken back to NLN for commissioning

STATE of H1: Earthquake
OUTGOING OPERATOR: Ibrahim
CURRENT ENVIRONMENT:
    SEI_ENV state: EARTHQUAKE
    Wind: 6mph Gusts, 4mph 3min avg
    Primary useism: 0.10 μm/s
    Secondary useism: 0.25 μm/s
QUICK SUMMARY:

H1 lost lock recently most likely due to a M5.4 earthquake off the western coast of Mexico.

Overnight H1 had a lockloss at 1245 with no IMC/FSS oscillation tags.

It is Saturday, so a Calibration is scheduled late morning, but thermalization requirements may push this out to the afternoon since H1, L1 are currently both DOWN and V1 has been Observing 15min.

SHIFT SUMMARY: 2ndary microseism is increasing, 2 locklosses this shift. We've been locked and observing for 35 minutes.
LOG: No log

• 23:49 UTC lockloss
  • 00:37 UTC lost it at TRANSITION_FROM_ETMX (IMC_REFL_SERVO_SPLITMON ran away)
  • 01:22 UTC NLN, 01:25 UTC Observing
  • 03:49 UTC Superevent s241130n
• 04:36 UTC lockloss
  • 05:27 UTC Observing

Lockloss at 04:36 UTC

Closes FAMIS 26344. Last checked in alog 81421.

For the CS MR_FAN3_170_1 looks to have gotten noisier 2 days ago.

For the OUT buildings EX_FAN1_570_2 got noticeably noisier two days ago and looks to be trending upwards.

STATE of H1: Observing at 160Mpc
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY:

About 100min of downtime for the 9hr shift (with a lockloss early in the shift and one near the end of the shift).  For speed, I nudged H1 to CHECK MICH FRINGES to help with DRMI (the 2nd lockloss' ALS locking was all automatic).

Chilly Black Friday with temperatures barely going over 35°F.  µseism looks like it might have slightly inched above the 50th percentile over the last 24hrts.
LOG:

• 1713 LOCKLOSS (with ETM_GLITCH tag for etmX); this lock was about 8.75hrs.
  • 1713-1820 Locking where ALSx & PRMI/DRMI needed to be touched up.
• 2349 LOCKLOSS (with an IMC tag for the lockloss, but RyanC assured that it didn't look like it was of the glitchy variety); lock was 5.5hrs.
  • Handing over this reacquisition to RYAN C to take H1 back to OBSERVING.

STATE of H1: Lock Acquisition
OUTGOING OPERATOR: Corey
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 3mph Gusts, 1mph 3min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.22 μm/s
QUICK SUMMARY:

• 23:49 UTC lockloss, we're relocking at PREP_DC
• Wind is low, microseism is calm
• I ran the low range check for the lock we just lost

23:49 UTC lockloss IMC tag, ASC and IMC lost it within 5ms of eachother. It looks like the ISS might have lost it first then 30ms later the FSS and ASC lost it.

Fri Nov 29 10:05:18 2024 INFO: Fill completed in 5min 15secs

TC mins -79C,-78C. New trip -75C.

H1 had a lockloss in fairly quiet conditions.  Lockloss had an "ETM_GLITCH" tag (ETMx, "zoom-in" attached); last time we had one of these was about 3-days ago.
IMC took a few min to acquire after lockloss.  ALSx locked, but was driven off by ASC to a pitch misalignment (tried touching up flashes via TMSx, but INCREASE FLASHES immediately took over).  DRMI looked ugly, so preemptively went to PRMI (which also looked bad) and then CHECK MICH FRINGES.

QUICK SUMMARY:

On this Black Friday, H1's been locked almost 7.5hrs w/ a range just under 160Mpc.  Decently quiet environmentally with microseism hovering just over the 50th percentile the last 24+hrs; winds are low.

On CDS Overview, CDS SDF was a yellow box for an SDF Diff for H1:CDS-LLA_CONTACT_25_ENABLE in the NO state---THIS WAS ACCEPTED (see attached).
