21:00 Kyle on site working on VPW

CH2M was supposed to knock down a stack today. Didn't see any evidence of it here on ground sensors or roof cam, but wall FOMs may not include relevant frequency bands?

STATE of H1: Observing at 51Mpc
INCOMING OPERATOR: Jim
SHIFT SUMMARY:  Observing for 4+ hours.  No issues after IA and relocking. 
LOG:  None

After a bit of a extensive IA followed by a short lock, we are back to Observing.  The range is down from earlier in the week at around 50 MPc.

    Secondary useism: 0.06 μm/s
QUICK SUMMARY:  Relocking after mystery lockloss post input pointing changes.  Currently at DRMI_LOCKED and will attempt to proceed further.  Cheryl suggests that if this lock doesn't work out, another IA may be helpful.

STATE of H1: Calibration
INCOMING OPERATOR: Travis
SHIFT SUMMARY:
LOG:

• Jenne and ThomasV were moving spots when a large shelf of noise started
• the noise lasted about 5-10 minutes, and cooincides with a large bump in noise on the 3-10HZ anthropogenic noise, though no proof that that was the cause
• H1 lost lock
• last 3 hours have been realigning H1
• arms locked in green nicely, but they are no longer aligned to the IR, so X arm in IR started locking at 0.3
• I had to move ITMX and ETMX at the same time in pitch and yaw to recover the X arm in IR
• had to center ASC QPD with SR2 to get SRC to lock
• in full lock, arms in green looked good, about 1.0, but COMM and DIFF beatnotes were way off, COMM was 2.2, DIFF at 1.2
• I used PR3 to bring COMM up to 4. something
• locking ALS locked well
• find IR had the X arm at 0.7 and Y arm at 0.5, so I tweaked PR3 to bring IR are signals up to were guardian would move on
• locked PRM, it was low, aligned it
• DRMI locked and ASC engaged, so hopefully this will make it to NLN
• handing off to Travis

After Robert finished his PEM injections, we wanted to try to change the pointing into the interferometer after IMC using the IM1 and IM3 to put IM4 Trans QPD back to the pre-EQ location, this seemed to help the range a bit as well as increase the power recycling gain.

Since we were convinced the pointing was satisfactory, we began to try to optimize the spot locations using the reverse A2L procedure using the June 18th data as a good reference.  However, this really screwed up the sensitivity so we're leaving the SOFT loop offsets back at zero.

So in the end, there's a bit of change to the input pointing, spot positions remain unchanged, A2L gains remain unchanged.

QUICK SUMMARY:

• H1 locked and made it to NLN without removing OMC whitening
• Robert to EY for injections
• currently Jenne and ThomasV moving beam spots

STATE of H1:  CALIBRATION ("PEM Injections")
INCOMING OPERATOR: Cheryl
SHIFT SUMMARY:

Violin Modes rung up while locking up!  Please watch Violin Modes to confirm Guaridan settings are OK (watch them around the VIOLIN_MODE_DAMPING_1 steps).
LOG:

• 20:17-21:02 OBSERVING
  • OMC_LOCK NO LONGER MANAGED  (to fix this, can:  "z write H1:GRD-OMC_LOCK_MANAGER ISC_LOCK")
  • Knocked out due to "Loading" a Safe.snap file to look at.  
  • Since we were out, I made OMC_LOCK re-managed by ISC_LOCK.
• 21:06-22:37 OBSERVING
• 22:37 Out of OBSERVING for coordinated L1/H1 PEM Injection work (Obs Mode:  CALIBRATION).
  • 22:47 Had a lockloss while Robert was doing ETMy ERM adjustments
  • Relocking now & looks like violin modes look OK.
  • Robert/Anamaria plan to have 1-2hrs of detector time.

Since there are no tasks on deck for H1, going to take this opportunity to get some multiple-coincidence data (w/ L1 & V1). 

There were some SDF Diffs:

• SUSITMy:  Related to MODE9 (this is due to violin mode damping), ACCEPTED
• ASCIMC:  Related to PZTs (this is due to IMC this morning), ACCEPTED

Guardian Note: 

Since OMC_LOCK was needed to go to MANUAL to REMOVE_WHITENING,

I made two BruCo scans, the first from before the Montana EQ at:

https://ldas-jobs.ligo-wa.caltech.edu/~brian.oreilly/bruco_1183356018/

the second from July 14th 0300 UTC at:

https://ldas-jobs.ligo-wa.caltech.edu/~brian.oreilly/bruco_1184036418/

Attached are the trends of the Oplevs (FAMIS #4736).

Do not see any pressing issues to worry about.

Last entry from Roam position 7, see 37334.

At Roam8, a meter or so further +X from Roam7, the spectra would suggest this location is not as quiet (wind response tilting) as Roam7.  However, this wind is from the NNW rather than our usual S or SW for previous views.  Also, while the Y dof seems more tilty for STS2-C (HAM5), at the lowest frequencies, HAM5 seems less tilty below 100mHz for the X dof.  I'm not sure if this conclusion is valid when the sensor is noisier during the quiet period???

Attached are the usual wind plot and sensor spectra.  The quiet wind time is 11 July 1200utc and the windy time begins 0230utc on 11 July.

Just posting an update on this -- the H1 PCAL Y RX PD reported displacement continues to decay, likely due to some temperature dependent clipping. This had been a part of the FRS Ticket 8328, but there's little we can do during an observation run to fix this. We've since closed the issue as LONGTERMFIX. AS such, I'll raise to an integration issue, and mark as WHEN VENT (similar to the promised work in Integration Issue 4700).

For now, recall that we've switched over to using TXPD as the calibration reference (see LHO aLOG 37166).
