TITLE: 11/02 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: TJ
SHIFT SUMMARY: The IMC has been very unhappy and the FSS has been glitching frequently this shift. HLID picket fence seismometer has also been glitching out this afternoon (Tagging SEI), after the locklosses the IMC would lose it again and relock after reaching READY this kept happening this evening. We just locked PRMI as of 05:00 UTC.

The left display of the Operator WS is flickering, unplugging and plugged it back in fixes the issue but only for like an hour.

LOG: No log

Lock#1:

• 23:29 UTC ENGAGE_DRMI lockloss
• 23:42 UTC CARM_OFFSET_REDUCTION lockloss #3, IMC and ASC_AS_A lost lock at the same time, zoomed in
  • 00:25 UTC Observing
• 00:52 UTC lockloss 31 minute lock :(
  • Lots of FSS glitches after this lockloss, the IMC kept locking then the FSS would glitch and kill it in ready. I put ISC_LOCK in down till it locked, this happened 6 times before it would hold it, then it lost it as soon as I moved on from DOWN, I watched the FSS_FAST channel grow until a glitch killed it seconds later. Then the 8th time was the charm and it held.
  • Despite these inital issues relocking was fine after the IMC actually held, automated relock in just over an hour
  • 01:58 UTC Observing
• 04:17 UTC lockloss 2:24 lock
  • The IMC locked and relocked a few times again in READY
  • DRMI doesn't look as good now
