TITLE: 03/08 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Ibrahim
SHIFT SUMMARY:

Two locklosses today which were straightforward to recover from.  One happened at the waning minutes of the calibration suite of measurements which is sad (EQ inbound, higher winds, and microseism increasing); this was tagged as a WIND + Calibration lockloss.

Also had 5-tours for our 2nd Saturday Tour day.
LOG:

• H1 was recovering from an ETMx glitch lockloss at beginning of shift.
• 1638 Back to Observing
• 1700-1715 Picked up around the Control Room before Saturday Tour visitors arrive (mainly putting lots of used scratch paper in the "data archive" (aka recycling bin), one coffee cup in dishwasher, one battery in battery recycling container, and organized chairs.
• 1815-1832 930am Saturday tour (cassidy)
  • 1955-2010 1030am Saturday tour (janos)
  • 2040- 1130am Saturday tour (mike)
  • 2125-2156 1230pm Saturday tour (amber)
  • 2245-2314 1:30 Saturday Tour (fred)
• 1911 Incoming EQ alert for M5.7 from southern japan
• 1930 Out of Observing for Saturday Calibration
  • Lockloss (presumably due to incoming EQ) during the last few minutes of the simulines measurement at 1958utc  :(
  • Had WINDY + Calibration tags for this lockloss.
• 1952 Noticed nuc25 PI Mode ndscope was not running for last 4-days---restarted it.
• 1958 LOCKLOSS (right before the Saturday Calibration measurement)
  • 2004-2024 Initial Alignment
  • 2122 OBSERVING....could have been a few minutes sooner, but for some reason a GRD_IFO in "AUTOMATIC OPERATION" failed to take us in automatically which is odd.
• 0002 EQ alert for another one south of Japan
• 0017 Lockloss....guessing it is EQ related since we had an alert for one, but we also have high microseism and winds
  • Proactively went for an Initial Alignment and now handing off to Ibrahim!
  • Late NOTE:  This lockloss has a WINDY tag with winds passing the 20mph threshhold, but we also had the earth moving with that incoming EQ from South Japan and rising usiesm...so, still think it's a toss-up.  Both locklosses with the South Japan EQ never had the picket fence go yellow, did not see any movement on ndscopes and really didn't look bad on seismometer bands, so chalking it up to a comedy of seismic noise teaming up to be an H1 foe.
