OPS OWL Mid-Shift Update
  1. Lockloss at 8:10 UTC due to DRMI unlocked - locking now
  2. Lock 1:
    • Had to go to increase flashes (both)
      1. Had to touch X significantly 
    • Took a while to get Find_IR
    • DRMI unlocked
      1. Need to go through PRMI
      2. Put SQZ_MANAGER in DOWN as per Vicky's request
      3. Touched BS when PRMI locked to overlay the beams 
        • As with yesterday (5/30), had to go through PRMI at which point I assisted guardian (after letting it try and fail for a small time) through touching PRM to get PRMI to locked. While attempting to acquire DRMI (1F), I touched the BS while looking at the AS AIR camera in order to align the "peanut" beams on top of one another.
      4. Got NLN at 9:33 UTC but got stuck at ENGAGE_PUMP_ISS while trying to get LOCKED_CLF_DUAL in order to achieve FREQ_DEP_SQZ. Fixed itself somehow after 27 minutes of stalling.
  3. IFO STATUS: In NLN and OBSERVING as of 9:59 UTC.
  4. Other: NUC 30 DARM FOM working but near-constantly glitching.
