TITLE: 11/02 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 157Mpc
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY: Currently Observing at 157Mpc and have been Locked for over an hour. We relocked many times today and relocking tended to take a bit long due to many locklosses, but for the most part was hands-off. The only things that required help were 1) during both initial alignments I ran today, when we got to aligning PRC, the IMC unlocked and could not relock - every time it would relock the FSS would glitch and unlock. To solve this, I waited until the PSL_FSS guardian was in READY_FOR_MC_LOCK, and then I paused it. Then, I waited for the IMC to lock and it would lock fine that next try, and once it had been locked for a few seconds, I unpaused the PSL_FSS guardian (tagging OpsInfo) and 2) one of the times when we were in GREEN_ARMS, ALS_XARM was stuck in CHECK_CRYSTAL_FREQUENCY, but taking it to UNLOCKED and then ETM_TMS_WFS_OFFLOADED fixed it right away.

15:17 Lockloss
    15:17 Started an initial alignment
        IMC lost lock when trying to align PRC
            - Every time it would relock, the FSS would oscillate and cause the IMC to lose lock again & FSS would lose lock
            - I paused the FSS guardian once the FSS was locked and then unpaused once the IMC was good and locked
    15:40 Initial alignment done, relocking

18:38 Lockloss
    18:38 Started an initial alignment
        - Same issue as before - during PRC the mode cleaner unlocks and cannot relock due to the FSS glitching and unlocking.
            Steps that have worked for me: (tagging Ops)
            1) Wait until the PSL_FSS guardian is in READY_FOR_MC_LOCK
            2) Once it is, pause PSL_FSS
            3) Wait for IMC to lock
            4) Once it has, unpause PSL_FSS
        - For some reason, even once the FSS and IMC were locked and we were aligning PRC, the ISS diffracted power was jumping all over the place
    18:58 Initial alignment done, relocking
        - ALS_XARM CHECK_CRYSTAL_FREQUENCY issue - toggling Force/No Force did not work, so I changed ALS_XARM to AUTO and then took it to UNLOCKED. I selected ETM_TMS_WFS_OFFLOADED and it locked immediately before I could troubleshoot further
