I don't see anything noteworthy in the lockloss scopes from the previous lockloss this morning. The relock was fully automated.
TITLE: 10/13 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 149Mpc
OUTGOING OPERATOR: Corey
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 2mph Gusts, 1mph 5min avg
Primary useism: 0.02 μm/s
Secondary useism: 0.17 μm/s
QUICK SUMMARY:
Update on outbuilding weather station restarts: After over a week of having to daily restart the mid and end station weather station IOCs at 4am for a failure in the previous hour, the last time we had to do this was Mon 9th Oct. This is similar to what happened in early January this year, for about a week the weather stations stopped updating around 03:20 in the morning, and then the problem went away by itself.
I did another round of serching h0epics's log files, crontab, anacron, etc. but found nothing which would cause this.
Decreased range in the IFO this morning vs last night appears to be due to DARM above ~200Hz. This shows up in the SQZ BLRMs too, attached plot. Today the PRC has 0.15W less than yesterday, but this is a normal fluctuation. Nothing has changed in the TCS system.
In response to Camilla's finding, and for her RH tests right now 73445, we have changed the sqz angle by changing the CLF DEMOD RF6 phase from 150 to 142. Blue BLRMS_5_DB_MON at 1.7 kHz improved maybe 0.5dB.

SHIFT SUMMARY: H1 has been locked for 25 hours. Some commissioning time and one earthquake passing through, otherwise a quiet evening. DIAG_MAIN went into error several times as I was testing a new checker, which has not yet been implemented.

The coefficientplots.py script used to generate the plots is still having problems with matplotlib; one workaround is to use the cds-py39 environment before running it with "conda activate cds-py39"
H1 has been locked for 21 hours and observing for the past 2.5 hours, range at 157Mpc.
Quiet evening so far after commissioning wrapped up; inspiral range is looking good after the LSCFF adjustments (see alog 73428).
H1 dropped observing at 23:22 UTC for commissioning while L1 is still down.
H1 is back to observing as of 00:30 UTC

SHIFT SUMMARY: Locked for 17 hours. Commissioning activities took up the morning, but we've been Observing since 12PT. Camilla and Jenne have been working on the LSC FF and have some new filters in place.

QUICK SUMMARY: H1 has been locked for 17 hours and observing for most of the afternoon.
To supplement lost flow from taking SF2 down, I manually rolled the axi-vane fan pitch from "12" to "8". Taking the flow from roughly 7500cfm to 10,000. T. Guidry R. Schofield
While Robert was doing some low-level commissioning (so, relatively quiet time), I had the NonSENS cleaning on again. Data is good from 17:34:13 UTC - 18:07:48 UTC (12 Oct 2023). It gave us about 7 Mpc. Since the LSCFF is being tuned, hopefully most of that will just be taken care of with the in-loop feedforward, since the cleaning is not yet approved for use in Observe.

We've moved the LSC FF from ETMX to ETMY PUM and turned on the new LSC FF filters measured in 73393.
This has reduced noise above 50Hz but increased noise below 50Hz, plots attached of the FF and DARM, compare gold to pink. H1 range is simular.
We've left this configuration, edited ISC_LOCK for this to be the new nominal and accepted attached sdfs. We plan to work to iteratively improve the filters in the next few hours with a new set of measurements we took this morning ~18:40UTC.
Jenne and I re-fit new filters iteratively to using the measurements we took this morning and loaded new filters into MICHFF and SRCL1FF, sdf safe and observe accepted and ISC_LOCK updated. H1 range is up ~7Mpc, plot attached, thin line is without cleaning.
We are hopeful that now the LSC FF is driven on ETMY, it will not need to be tuned as often as won't be effected by changing charge ETMX.
Attached MICH excitation comparison (new trace is light blue) which shows we are putting in more MICH 20Hz that previously but this isn't visible in DARM. Note that during the day today Tyler/Robert has turned off fans, reducing peaks ~25, 40, 52Hz 73424.
We checked that these LSC FF filters are not injecting any low frequency noise into DARM.
Locked for 13 hours. We have been taking opportunistic commissioning time this morning while LLO is down from seismic noise, but have just went back to Observing.

We took squeeze data with PSAMs on ZM4 and ZM5 both at 120V, and four squeeze angles. Summary screenshot here, with these trends of squeezed BLRMS. All of the following data was done with frequency dependent squeezing.
With ZM4/5 at 120/120 V, +/- mid squeeze have noticibly different misrotations across the band. In alog 71902 from Aug. 2 with PSAMS at 200/200V, we didn't see strong misrotations down to ~80 Hz. From FDS data on Aug 2, compare today's green/blue lines to the green and yellow +/- mid squeeze lines in this plot.

I took more data with PSAMS ZM4/5 = 200V/200V, using the same injected sqz angles as above.

We followed up by checking ZM Sliders to see if there is misalignment with different PSAMS was a factor in addition to the mode mismatches from changing PSAMS. There seems to be a large static alignment shift from changing PSAMS, we're not sure if it is fully compensated by ASC especially in yaw. We might do more measurements tomorrow to follow up.

*+Mid SQZ: ZM6 was not flat for the 200/200 squeezing. It was increasing in P and Y for +Mid SQZ, didn't seem to reach the steady state. It seems like the ASC is keeping up better with 120/120 because the angles converged, whereas the angles of ZM5 and ZM6 for the 200/200 case kept increasing and did not reach steady state in the time given.
ASQZ: ZM5 pitch for 120/120 has some shaking, ZM6 pitch is rising and yaw is dropping
