TITLE: 10/06 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 149Mpc
OUTGOING OPERATOR: Oli
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 12mph Gusts, 9mph 5min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.21 μm/s
QUICK SUMMARY:

All is nominal for H1 thus far this early-evening with H1 approaching 24.5hrs of being locked.  Slight increase in the microseismic band for the last 8hrs & winds are mostly under 10mph.

I've made a few updates to my script that graphs the Inlock and OPLEV charges and I've run the code with the latest measurements and included a same time scale (6 months) minute trend of Kappa TST (H1:CAL-CS_TDEP_KAPPA_TST_OUTPUT) that I've scaled the Y-axis a bit for better readability. The codes located at /ligo/home/ryan.crouch/Desktop/Charge_measurements/compare.py and you need to be in the nds2utils environment to run it (conda activate nds2utils). I've also included a solo unmodified Kappa trend.

The ETMY charge values seem to be trending down towards zero. The ETMX charge values seem to be converging towards zero as well now (yay?). Kappa_TST appears to be slowly increasing, or slowly decaying with a sign flip.

I've added a test into DIAG_MAIN that shows "Check PSL chiller" when any of the PSL chiller status channels are non-nominal (ENABLED, FLOWERROR, or ALARM). The most likely scenario when this message will show is when the chiller is at a low water level, since if the chiller flow stops or the chiller isn't enabled, the NPRO can't run at all.

Gerardo confirmed a good fill curbside.

Oli, Camilla. We popped into commissioning to adjust the ITM ring heaters up from 0.05W/segment at 17:15UTC, now ITMX is at 0.49W and ITMY 0.05W. Accepted changes in sdf. Back in observing while the slow thermalization happens, plan to revert to nominal in 3 hours at 20:15UTC.

This weeks past ring heater tests are 73289, 73093 and 73272.

Similar to Thu morning, the picket fence server data update slowly degraded overnight and eventually stopped updating.

All was working until 02:48 PDT when some data cycles started taking about 35 seconds (normally it cycles over 3 seconds). This transition is shown in the top trend.

About an hour later at 03:48 the frequency of the long reads increased and became regular (bottom plot).

At 07:13 the updates stopped completely, this is the current situation.

STATE of H1: Observing at 148Mpc
OUTGOING OPERATOR: Ryan C
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 7mph Gusts, 4mph 5min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.17 μm/s
QUICK SUMMARY:

Up and Locked for 16hours. The dustmon alarms for LVEA6 300nm and LVEA10 300nm are both going off, but it looks like their counts maxed out at 70 and 170 respectively about 3 hours ago, so not too high.

Picket fence script looks broken still.

STATE of H1: Observing at 151Mpc
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY:

- Arrived with H1 locked, waiting for ADS to converge

• OBSERVE @ 23:07

- EX saturation @ 0:35

- DM 102 alert for PSL102 500 nm, trend attached, looks like the counts got up to 100, will monitor

• Also had an alert on DM 6 in the LVEA (HAM 6 area), 300 nm, peak counts at 140, looks to have calmed back down shortly after

- 1:43 - EQ mode activated, no alert from verbal for any EQ, peakmon counts are hovering around 6-700

• Looking at USGS, there did seem to be a small EQ from Alaska ~1:39 UTC, so I'm assuming this was the cause of the ground motion
• Another EQ alert @ 1:50, this was a 6.1 from Japan, though according to USGS...we'll see if we can make it through this one
• Looks like we made it, back to CALM @ 2:46

- 3:51 - another EQ, this one was a 5.4 from Panama

• 4:03 EQ mode activated, back to CALM @ 4:13
• and another from Japan @ 6:05, 5.6

LOG:

No log for this shift.

Couple EQs that we were able to ride through, ground motion has since settled. Otherwise, H1 appears to be stable, currently locked for 4 hours.

QUICK SUMMARY:

- IFO is currently at NLN, waiting for ADS to converge

- CDS/SEI/DMs ok

We've been running with both the cleanrooms in the Optics Lab and the flowbench furthest from the door running. Robert said that in the past (23169 ?) we haven't seen noise from these but should repeat the test now we have higher sensitivity.

Cleanrooms and flow-bench turned off for 8 minute intervals at below times (-/+5 seconds).

• Turned off 22:40:00  to 22:48:05 UTC

• Turned off 22:56:00 to 23:04:00 UTC

• Turned off 23:12:00 to 23:20:00 UTC

Turned on a small cleanroom inside the filter cavity enclosure at 21:45:10 UTC, allowed to the cleanroom to run for 15 minutes, then turned it off.  Turned cleanroom back ON at 22:00:00 UTC, once again I let the cleanroom run for 15 minutes.  Cleanroom was not moved and it is now off.
