Sheila, Camilla. Last done in 80451, followed those instructions.

Before translating the crystal, we reduced the green H1:SQZ-SHG_LAUNCH_DC_POWERMON power from 30mW down to 6mW. After we finished, we brought this up to 15mW and still could lock the OPO with 80uW on H1:SQZ-OPO_TRANS_LF_OUTPUT and around 6 on the ISS controlmon. Meaning our losses reduced significantly.

We moved from the 3rd spot from the left photo to the 4th spot from the left photo ( 34 x steps of 50 to the right and then 19 x steps of 10 to the right).  We have previously used the 2nd, 3rd, and 5th spots from the left, there is 6 spots in total.

Measured NLG to be 8.8 (0.0787/0.00892, 76542). This is lower than what we usually run with 11 to 17 so means that this new spot has less losses but a worse NLG.

FDS is the same but ASQZ lower. Shiela said that this good and is expected with lower losses and mean there can be less mis-rotated ASQZ injected. Plot attached.

Tagging OpsInfo: This change will mean that for the next week or so we'll need to more regularly adjust the OPO TEC temperature, instructions are in 80461. Should be done pro-actively when relocking and if range is low in observing.  If you adjust while in Observing, please tag Detchar in your alog.

    Primary useism: 0.06 μm/s

QUICK SUMMARY:

Observing and have been Locked for over 5 hours. Secondary microseism looks like it's been creeping up.

SHIFT SUMMARY: Quiet night, we stayed locked the whole shift, 10.5 hours as of 06:00 UTC. 2ndary microseism has risen rapidly over the past 3 hours.
LOG: No log.

STATE of H1: Observing at 160Mpc
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY: Currently Observing and have been locked for 5 hours. One lockloss today due to an EQ, but relocking was easy. The only problem I ran into was during initial alignment SRY couldn't catch, but I just had us go through SR2 align again and then we were fine. No other intervention was needed from me.

    - Ran an initial alignment
        - Was having trouble with SRY so I reran SR2 and that worked

STATE of H1: Lock Acquisition
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY: Currently relocking and at MAX_POWER. Most of today we were Locked and Observing, but this one lockloss so far hasn't been too bad to relock from. Only issue I had was that ALSY took forever to lock and I ended up having to adjust it manually just a couple of steps.
LOG:

19:30 Dropped Observing and went to NLN_CAL_MEAS for calibration measurements
20:04 Back to NLN and Observing

22:50 Lockloss
    - I had to touch ALSY because it couldn't lock after 30 minutes of trying, even with SCAN_ALIGNMENT. Just needed to be adjusted a tiny bit in P
    - Ran an initial alignment
    - Continued relocking
