TITLE: 03/28 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 152Mpc
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY:

Most of today was for Commissioning and then PEM Injection prep/measurements. 

H1 was locked for a good part of the shift, with (2) locklosses.  Able to relock after 20+hr lock without needing an alignment (but definitely needed to correct lots of pitch misalignment. 

Had a high winds storm pass through during the last hour of the shift, highest wind value from our wind sensors was 57mph from the Corner Station (see attached).

LOG:

• 1502 Optics Lab cleaning (karen)
• 1539 Out of OBSERVING for commissioning/pem injections
• 1539 Beam Jitter measurements + input pointing changes (sheila)
• 1541 EX accelerometer fixes (robert)
• 1558 IMC CM board measurment at racks (sheila)
• 1600 Lockloss  (Sheila was heading out at this time and might have just entered the LVEA, but not totally certain.)
  • Lock1:  Xarm was way off in pitch (even after an INCREASE FLASHES).  Was off in pitch and mainly got it back with TMSx.  ALSO---PRMI flashes were OFF in pitch (PRM pit adjusted).  DRMI flashes were also OFF in pitch (SRM pit adjusted).  Saved ~15min by doing all this Pitch BabySitting vs going through an alignment.  Back to NLN at 1712 (w/ CAMERA SERVO complete at 1716)
• 1622 SEI_ENV transitions to USEISM
• 1635-1707 Facility check in FC beam tube enclosure (chisS)
• 1718 Transition LVEA to HAZARD!! (Camilla for Robert)
  • She did not enter LVEA to transition, so she most likely did NOT cause lockloss.
• 1729 Lockloss!!
  • Lock2:  No issues or action needed
  • 1814-NLN & 1820-Camera Servo complete
• 1737-1754 Checking HEPI @HAM1 (jim)
  • While at HAM1 Jim noticed audible noise---believes it is Paging System speaker
• 1739 Grabbing wipes in Fire/Hazardous waste bunker (kim)
• 1740-1825 Attaching camera to viewport + Looking for Laser Vibrometer in LVEA & then EX (robert)
• ~1755 Paging System powered OFF (after Jim noticed ~60Hz noise from speaker in the LVEA).  [fil]
• 1806-1819 ADF Squeezer rack work---entering via output/side door near roll-up door (Daniel)
• 1835 IMC photos (robert)
• 1835 Input pointing walks (jennie, francisco, sheila)
• 2000-2016 Hanford High Astronomy class in control room (cassidy.alan)
• 2010 Vacuum checks at MY (janos)
• 2133-2218 Turning off shaker at EX (robert)
• 2135 Setting up StarLink internet antenna at the VPW (dave)
• 2145 Big storm rolls through (gusts approaching 60mph)
• 2219 Taking laser vibrometer to LVEA (robert)
• After winds calmed down after the windstorm and when we could start locking, DRMI locked up fine, but have lost lock in a few steps before CARM OFFSET REDUCTION.  Jennie mentioned if we continue having issues we can have her restore input pointing to what it was earlier in the shift.
