TITLE: 11/23 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 161Mpc
INCOMING OPERATOR: None
SHIFT SUMMARY:

It has been a shift with a return to decent locking with H1 unlocked ~2.5hrs for the shift.  Saturday Calibration was run (coordinated with LLO).  Overall locking was fairly easy although the ALS took a bit of time (not bad), and DRMI locking was a little tough and needed PRMI/CHECK_MICH_FRINGES.  But after that locking has been automated.
LOG:

• 1633 Lockloss (after 5hr55min lock)
• Locking Notes:
  • Green arms:  x-arm looked off in pitch and mostly improved via TMSx in +pit, but then let INCREASE FLASHES run for both arms.
    • ALSy would have its alignment driven off, so quickly took down and tweaked up mainly via tmsy (still not great, but made it)
  • DRMI:  Had to go to PRMI.  Still looked off, so touched PRM and then BS in pitch (due to AS flashes) & it locked.  During ASC offload, AS camera went from pitch misalignment to yaw misalignment on the camera and it stuck with that as ASC offloaded.  For DRMI, eventually locked after 4+min, but....
    • 1702 DRMI Lockloss (non-DOWN)
    • 1757 Back to NLN
• 1921 Incoming M5.9 Fiji EQ alert---No issues riding through it.
• 2036-2037 Accidental Drop from OBSERVING due to Operator Error
  • For the next lock, there is currently an ISC_LOCK notification saying, "ALS_XARM:  STOLEN by USER"
• 2100-2132 Calibration
• 2221 Lockloss (after a 4hr24min lock)  
  • ALS locking once again was not smooth.  Required several rounds of INCREASE FLASHES.  And even after that when the arms would lock, they would have noticeable oscillations (for the y-arm the powers had a 5sec period oscillation which would cause a lockloss)  But ISC LOCK eventually moved on.
  • DRMI had flashes, but similar to last lock it wasn't quite there.  I took H1 straight to CHECK MICH FRINGES after a few minutes, and rest of ISC_LOCK was automated.
  • 2329 OBSERVING
• 2349 PI24 begins ringing up & was damped down within a couple minutes.
