At ~21:00 UTC, LLO called to verify that we had received the GRB alert.  Again, as happened previous 2 days (alog 36772 and 36792), we did not receive the alert.  Dave is looking into this issue.

Created a command-line HWS WF plotting tool. See: https://alog.ligo-la.caltech.edu/aLOG/index.php?callRep=34263

Locked for ~4 hours.  Range is a bit low.  It has been suggested that this is due to low PRC gain.  We'll wait for the next lockloss to address this.

Laser Status:
SysStat is good
Front End Power is 33.99W (should be around 30 W)
HPO Output Power is 157.2W
Front End Watch is GREEN
HPO Watch is GREEN

PMC:
It has been locked 5 days, 21 hr 11 minutes (should be days/weeks)
Reflected power = 16.07Watts
Transmitted power = 59.44Watts
PowerSum = 75.51Watts.

FSS:
It has been locked for 0 days 4 hr and 9 min (should be days/weeks)
TPD[V] = 3.485V (min 0.9V)

ISS:
The diffracted power is around 2.8% (should be 3-5%)
Last saturation event was 0 days 4 hours and 21 minutes ago (should be days/weeks)

Possible Issues:

• Front End Power is 33.99W (should be around 30 W) - currently Ops overview has the input power as exactly 30.0W, so maybe this difference comes from using a different sensor?
• The diffracted power is around 2.8% (should be 3-5%) - this is just below the bottom range of the range that's good, close enough that it's not currently a problem, but something to watch if if drops any further.

Summary of the DQ shift from Thursday 8th June to Sunday 11th June (inclusive), click here for full report:

* Very good start to the post-commissioning break with a single lock that extended the whole weekend and duty cycles of 19% (thursday), 72% (friday), 97% (saturday) and 100% (sunday) for the period of this DQ shift.

* Range sensitivity stable averaging around 64 Mpc.

* Not an eventful DQ shift, despite some strong winds and Earthquakes in Mexico. However notice that the only lockloss of Friday lasted 3:30 hours and for a long time LHO had trouble progressing beyond DRMI, dropping out of lock widly (AS camera spot swings wildly and AS90_OVER_POP90 channel has huge values). This required running and INITIAL ALIGNMENT which had issues for a while until LHO realised that this was the first initial alignment run since changes on Wed evening, when the green PZT pointing and green ITM camera setpoints were reset. This changes were undone for both arms. Things worked better after this.

* Interesting PyCBC live glitches on Friday (one Koi fish and another of the type previously identified as related to radiation pressure) and Saturday (blip/chirp? glitch suggested as maybe being related to computer issues).

* On Saturday highest SNR Omicron glitches correlates with scattering of H1:SUS-PRM_M1_DAMP_L and H1:SUS-SRM_M1_DAMP_L, caused by Earthquake in Mexico.

* On Saturday very short consecutive drop outs of Observe mode due to TCS ITMx laser losing lock.

TITLE: 06/12 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing
OUTGOING OPERATOR: Patrick
CURRENT ENVIRONMENT:
    Wind: 12mph Gusts, 9mph 5min avg
    Primary useism: 0.10 μm/s
    Secondary useism: 0.14 μm/s
QUICK SUMMARY:  Just made it back to NLN and Observing.  No issues with relocking after Patrick's IA.  Had to accept a few SDF diffs, 2 for ISCEX and ISCEY that were 10^-17, so didn't bother taking a screenshot.  The H1SYSECATX1PLC2 diff I accepted is attached for reference.

TITLE: 06/12 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Earthquake
INCOMING OPERATOR: Travis
SHIFT SUMMARY: No issues until earthquake. Finished initial alignment. Attempting to relock.
LOG:

12:23 UTC Noticed that the earthquake plot on the top display of nuc5 had disappeared. Restarted nuc5.
12:33 UTC Verbal alarms notice of incoming earthquake
13:15 UTC Lock loss
13:59 UTC Changed observatory mode from lock acquistion to earthquake. Should have done so earlier.
14:15 UTC Starting initial alignment
15:03 UTC Initial alignment done

I received a verbal alarm notification of an incoming earthquake. It was not clear at first which earthquake was being seen. I now believe it must be the 6.3 magnitude one in Greece. It seems that Seismon saw it first, then the USGS webpage and then Terramon. Neither the USGS webpage or Terramon saw it before it arrived. Is the verbal alarms notification looking at Seismon?

12:33 UTC Verbal alarms notice of an incoming earthquake. I do not see anything with an arrival time closer than 05:14 PST (12:14 UTC) on Terramon. I'm not certain how to read seismon. It seems to predict a 6.4 earthquake, but I don't see one of this magnitude on USGS.
12:43 UTC Spike on seismic BLRMS.
13:15 UTC Lock loss

No issues to report. Lock is almost 64 hours old.

SHIFT SUMMARY:
LOG:

03:05UTC  USGS reports 5.6 near Chile at 2:43UTC. Seismon hasn't reported it as of 3:12UTC

3:40UTC first signs of ground motion on EQ BLRMS .3um/s. Terramon still not updated. Seismon isn't either.

1:19:45UTC Got this error. Have no idea what this is. It doesn't seem to have broke anything o my present knowldege.

@ 00:21

I, however, did not get the alert. I checked the INJ_TRANS node and it was still in the nominal 'wait' mode. I then called Keita inquiring as to wether I should manually KILL injections to which he agreed I should.

Had a friendly local stop by the site for a lunchtime snack.  Apparently Robert isn't the only one who likes the berries on the trees.  See pics.
