TITLE: 05/05 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
SHIFT SUMMARY:

Calibration & Commissioning time (as well as some LVEA incursions) today.  With one seismic lockloss.  
LOG:

  • 1635-1659 Checking to see if additional help needed (travis)
  • 1816-1852 Checking out wind fence (mike)
• 1516 Back to OBSERVING (after accepting filter diffs for L1_DAMP with ITMx & ETMy)
• 1519-2001 EY transitioned to Fence Work
• 1550-1602 Optics Lab cleans/checks (kim)
• 1618 Huge glitch seen on the running DARM dtt of nuc30 (all signals went up!)
• 1626 Running pydarm calibration measurement (corey,jeff)
• 1644 Verbal Alarm updated for lower-threshhold PI Mode alerts (ryanS)
• 1805 Pcal lab work (tony,dripta)
• 1806 LOCKLOSS
• 1815-1825 checking for water leaks in lvea (richard)
• 1819-1842 s/n checks (fernando, marc)
• 1819-1858 CER accel on PEM rack (marc, adrian)
• 1828-1834 dark measurements while we have seismic noise (elenna)
• 1830-1856 Turning on Hepta pump at EY (travis)
• 1835-1847 IMC WFS Centering (tj)
• 1953 back to NOMINAL LOW NOISE & taken to NLN_CAL_MEAS for calibration measurements (jeff)
• 2038 OBSERVING
• 2130 Picking up parts around EY wind fence---no operation of heavy machinery (randy,mitch)
• 2137 COMMISSIONING (jennie)
• 2218 Updating filter coefficients for PCal (rick)
• 2239 ISC_LOCK load by elenna

LOCKING NOTES:

• IFO locked before shift.
• 1806 lockloss (5.5hr lock) due to observed seismic motion (possibly 5.9 Japan eq? w/ 20min arrival time)
• For a dead PRMI, BS was moved quite a bit in negative PIT to get it to acquire (PRM pit in both directions didn't work & BS positive pit didn't help)
• Other than that, no other intervention required to get back to Nominal Low Noise (once seismic noise died down).
