TITLE: 07/10 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Ibrahim
SHIFT SUMMARY: Currently relocking and in ACQUIRE_DRMI_1F. We've been struggling the last hour+ due to the wind picking up. Earlier in relocking, we were seeing some ALSX crystal frequency issues, but they thankfully went away pretty fast.

THE LVEA IS LASER HAZARD

Three lock acquisitions during my shift today:

1st) went well after running an initial alignment, but we did have a couple issues at higher level states:
- In INJECT_SQUEEZING, we noticed the 1 Hz ringup happening again. We did what Elenna mentioned in 85643 and upped the CSOFT P gain from 20 to 25. This worked to slowly fix the ringup (85649)
- The filter cavity wouldn't lock. It was unlocking when it got to TRANSITION_IR or FC_ASC_ON. I checked H1:SQZ-FC_TRANS_C_LF_OUTPUT, and it was already pretty good at around 116, but I was able to adjust FC2 to get it up to over 125. We were still losing the filter cavity after this, so I checked what was done when we had this issue a couple weeks ago (85390). I was able to confirm from checking those same channels that we were in a good spot for all of them. Sheila mentioned adjusting the OPO temp, and that worked
2nd) went quickly and I just needed to help ALSY
3rd) current relocking, struggling with DRMI/PRMI, ALSX crystal frequency, and the wind

21:55 Lockloss
    - Check crystal frequency issues, but not for very long
    - Couldn't lock DRMI, cycled through PRMI, MICH, etc, so decided to run initial alignment
    - Wind started going up, making it hard to keep ALS locked
