TITLE: 06/16 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
SHIFT SUMMARY:

Decent shift with no EQs which knocked us out (appeared to ride through a Japan and Panama EQ), but an EY wind probably caused a lockloss (the other one most likely from a HAM1 ASC FF filter change).  Reacquisition was fairly good (except during the 90-min wind storm.

LOCK#1: (2335-2357) After a very short OBSERVING segment

• Xarm green needed INCREASE FLASHES
• LOCKLOSS at OFFLOAD DRMI
• During this lock I was backing out the HAM1 ASC FF changes.

LOCK#2:  (2358-0056)

• 0050 Verbal says we are at NLN, but....(orange)
• 0056 Camera Servo completes & green NLN
• 0057 OBSERVING

LOCK#3: (0339-0459)

• This occurred during a 90min pick up of wind (mainly at EY), but interestingly, X-arm green had trouble relocking.
• To speed getting back to Observing, I went directly to PRMI.  Then ISC_LOCK did the rest.

LOG:

• 2317-2326 Elenna running a measurement/test while H1 is hanging out in the OMC_WHITENING state waiting for violins to calm down after the EQs (almost to NLN).  She ACCEPTED some SEI_PROC SDF changes for HAM1 Feed Forward.
• 2328 Back to OBSERVING!
  • 2334 And then a lockloss (which had a 90min ring up of ASC's MICH_P).
• 0043 Incoming EQ notification received on Verbal (Hokkaido M5.6)
  • 0046 Start to see EQ on picket fence and 0.03-0.1Hz BLRMS.
• 0057 Back to OBSERVING
• 0110-0142 Stopping and picking up pump from MY and bringing back to CS Mechanical Room (Janos)
• 0139 Run down Xarm (Brice)
• 0336 LOCKLOSS
• 0330-0525 Winds w/ peaks above 30mph (w/ EY highest)
• 0459 OBSERVING
• 0542 PIMode 31 alert, but was automatically handled.
