Mid-Shift Summary

This doesn't seem to be causing any glitching anywhere but the 3-10 Hz anthropogenic Z-axis has been climbing for the last two hours. This is also translating into the 10-30Hz BLRMS too. I don't see anything correlating with this.

Nothing else to report. H1 going on 5.5hours locked. Livingston dropped a couple of times. Still observing.

    Primary useism: 0.01 μm/s
    Secondary useism: 0.06 μm/s
QUICK SUMMARY:

Arrived to find a2l needing to be run and Livingston was down, so I did. Dr Kissel is here measuring and plotting. Travis had nothing to report. Looks like business as usual.

First attempt at Measuring High Frequency UIM Dynamics for Non-ETMY SUS QUADs
J. Kissel

Having finished the BSC-ISI drives early and with an hour to spare, I spent ~30 minutes tuning up templates to find if other QUADs than ETMY have the same kind of spurious high frequency dynamics on their UIM stage; a part of the approved end-of-run close-out measurements for the CAL group (see JRPC page). 

ETMY was confirmed to have far-from-simple-f^(-6)-roll-off in UIM actuation to test mass response above 100 Hz back in ER10 (see LHO aLOG 31603), so I was copying those templates.
Unfortunately, I was only able to complete one frequency band of broad-band injections for ETMX, and then I broke the lock on the second band trying to get more SNR.

The data I did get lives here:
/ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/H1/Measurements/FullIFOActuatorTFs/2017-08-06/
    2017-08-06_H1SUSETMX_L1_PCAL2DARM_HFDynamicsTest_100-250Hz.xml
    2017-08-06_H1SUSETMX_L1_iEXC2DARM_HFDynamicsTest_100-250Hz.xml
which was enough to show, indeed, some nasty resonant feature in UIM actuation in that band.

In the fullness of time, I'll process, plot, and post this data once I get the rest of the suite as I'd had before, but processing the broad-band ISI injections is a priority at the moment.

Note: taking this data required me to briefly turn off all calibration lines on PCALX (333.9, 1083.3, and the roaming line which was at 2001.3 at the time of lock loss). However, all was restored after the lock loss, and the lines are back on wit the roaming line driving 2001.3 again.

~3 Hrs IFO Time for Commissioning; More BSC ISIS ST2 Drives on Test Mass SUS
J. Kissel

I spent 2.5 hours of IFO time today (or 3 hours even if you consider the lock-loss likely caused by me, and recovery from a part of it) gathering some more data on the recently found coupling between BSC-ISI's ST2 and DELTAL_EXTERNAL (see LHO aLOG 37752). 

Today, I drove in RX/RY (Pitch for each arm) and RZ (Yaw / Longitudinal for all) instead of X / Y (Longitudinal for each arm).

The templates for the drive live here:
/ligo/svncommon/SeiSVN/seismic/BSC-ISI/H1/Common/Data/
    2017-08-06_BSCISI_ST2_BB_RXRY_Injections.xml
    2017-08-06_BSCISI_ST2_BB_RZ_Injections.xml
However, they don't yet contain references for all times where I've driven. That'll come as I gather data from the frames. I'll recommit once I'm finished gathering all the data and plotting it.

Plots and Analysis to come.

Observing at 21:59 UTC

Relocked without any issues, just the usual tweaking of ETMs to get ALS to lock.  Sudarshan called about the lockloss and said that likely the PCal X HF line would be reverted to a 1501.3 Hz due to the lockloss, and asked me to change it back to 2001.3 Hz when at NLN.  I did so. 

SDF diffs accepted in order to go to Observe (see screenshots).  These are the same SDF diffs, but inverted, that Ed accepted at the last lockloss (see aLog 38009).  Should these become unmonitored, or is something else bad going on here??

Lockloss 21:22 UTC

Either Kissel measurements or incoming EQ.  Or some combination thereof.

PCal X HF line changed from 2501.3 Hz to 2001.3 Hz

Sudarshan called and requested that I change the PCal X high frequency line to 2001.3 Hz (previously 2501.3 Hz).  This was done at 20:06 UTC.

Ops Day Mid-shift Summary

No issues and lock is 40 hours old.  Kissel just showed up on site and plans to do some noise investigations (approved by Vern), so we'll likely be out of Observing shortly.

QUICK SUMMARY:

H1 was handed off to me following a double GRB which Gary Traylor informed me was the same one duplicated. Chatter on the EM follow-up channel on Teamspeak gave me clearance to return INJ_TRANS node back to inject success. This was done in concurrence with te LLO operator.

GRB alert (?) 22:46 UTC

We received a GRB alert at 22:46 UTC as reported by VerbalAlarms.  LLO confirmed that they did NOT receive this alert and GraceDB shows no GRBs around this time. Hmm??

Gary called back from LLO and confirmed that they finally did receive the GRB alert.  Still nothing on GraceDB however.
