STATE of H1: Observing at 68Mpc
INCOMING OPERATOR: Ed
SHIFT SUMMARY:  Observing for ~5 hours.  No issues to report.
LOG:  None

To run A2L while LLO is down.

IMC_LOCK guardian was reloaded which dropped us out of Observe.

CURRENT ENVIRONMENT:
    Wind: 16mph Gusts, 13mph 5min avg
    Primary useism: 0.04 μm/s
    Secondary useism: 0.09 μm/s
QUICK SUMMARY:  No issues handed off.  Lock is 19 hours old, but latest Observing stretch is only 2.5 hours old due to dropping out of Observe to change SEI Config for EQ and another drop for some commissioning.

23:09 Drop out of Observe so Sheila can move one of her dither lines.

SHIFT SUMMARY:
Activities:  all times UTC

• 18:34-18:36 - out of Observe for SEI change, see earlier alog for explanation
• H1 remained locked during the earthquake in Earth_Quake_2 SEI configuration!
• 20:00-20:41 - out of Observe for Sheila's WP#7062, and SEI was set back to WINDY
• 20:58 - computer in CER was on, powered off remotely
• H1 in Observe since 20:41UTC

As described in WP 7062, I have turned on alignment dither lines for PR3, ETMX, and ETMY.

The attached script turns on the lines and sets up the demod matrices, although I don't think it should be necessary to turn the lines off. The attached spectrum shows the new lines in DARM and PRCL at 6.7 Hz (ETMX Pit), 8.1Hz ETMX Yaw, (8.43Hz ETMX yaw), 7.4 Hz ETMX pit, 8.8 Hz ETMY yaw, 13.2 Hz PR3 PIT and 14.8 Hz PR3 Y.  These lines are on for the first time in this lock stretch (starting around 20:30 UTC Jun 28th).  I am hopping to leave them on for a few days/up to a week to get some data. 

The motivation for this is to leave these lines on for several days, to see if using a dither to replace some of QPDs would help to make our jitter coupling more stable over time.

Edit: Keita and Jeff K were concerned about the line at 8.1 Hz potentially causing a problem for calibration, so I moved it to 8.43 Hz.

• 2017-06-28 18:20:53 UTC 30.419°S   177.671°W 10.0 km depth
• 18:29:41 UTC - verbal alarm - incoming earthquake
• Terramon is not connecting - no information
• USGS reported the EQ after Seismon - exact delay is unknown
• 18:36:41UTC - H1 out of Observe, when seismic state changed from Windy to Earth_Quake_2, and a channel triggered SDF (no other changes to H1)
• 19:05:30UTC (approx.) - H1 ASC signals start to show large amplitudes
• screenshots attached were taken between 19:13-19:15UTC
• 19:24UTC - H1 is still locked, and ground velocity is now decreasing

Based on recommendations from Jess McIver, a full report based on the following summary can be found here- https://wiki.ligo.org/DetChar/DataQuality/DQShiftLHO20170622

Thursday the 22nd
		○ Knocked out of lock overnight by earthquake in Guatemala, regained it around 15:50 UTC. Microseism at 0.03-0.1 Hz reached 10 um/s, 0.1-0.3 Hz reached ~1 um/s.
		○ Also had reasonable high winds over night, in the ~25 MPH range.
		○ Used most of the morning for signal injections since LLO was down.
		○ Right around 20:17 UTC, noticed cross-frequency glitch, across 100-800 Hz, which rung up and then down within about 1 minute. Since other fellows hadn’t seen this, we investigated a little more. A SUS MC2 damping channel had coupling with a bunch of other subsystems and channels inside the OSB but they don’t correspond to any seismic peaks so I’ll need some DetChar help if we want to analyze further.

Friday the 23rd
		○ Some small range drops overnight due to overflows but morning was quiet otherwise.
		○ Mid day, we had an event alarm (G250171 in GraceDB) but it turned out to have a high false alarm rate.
		○ Except for a few overflows, we were steady throughout the day. HVeto did show another seismometer/accelerometer blend channel as the winner for the day, though, which was again coupling to a ton of other seismic isolation and stability control channels and without clear microseismic disturbances.

Saturday the 24th
		○ Some small range drops overnight due to overflows and “small earthquakes” (according to Alogs).
		○ Saw more cross-frequency glitches at 16:13 UTC and 16:50 UTC, which were across 10-1000 Hz, but they were single points and the earlier one seemed to correspond to spikes in Z-axis microseism. I didn't determine a clear cause for the later one.
		○ Quiet shift otherwise.

Sunday the 25th
		○ Range was all over the place today.
		○ Lost lock twice overnight. Operator didn’t report a clear cause in the Alogs and the PEM channels didn’t show any smoking guns.
		○ An earthquake in the South Pacific knocked us out of lock again mid-day, and instability knocked us out of lock two more times later in the day.

We have made a few changes to the way the guardian manages the ISS second and third loops that we think will allow us to use the third loop and not have locklosses when DC coupling the third loop

• We have changed IMC_LOCK so that it now manages the input and output from the ISS_THIRDLOOP_SERVO filter, so we can avoid confusion about when the third loop will be on or off.
• Before the second loop is DC coupled, the third loop gain is set to zero.
• We made the code that engages the third loop into a function that is now called twice, in the states POWER_UP_TR_CLOSED which is requested by ISC_LOCK in INCREASE_POWER and once in NOMINAL_TR_CLOSED which is requested in NOISE_TUNNINGS
• We increased the ramp time used for engaging the third loop, from 3 second to 10.  We hope this will decrease the transient that sometimes unlocks the IFO when the third loop is engaged with DC coupling on.

In order to facilitate drag-and-drop into dataviewer, I've edited all SUS type's coil driver monitor MEDM overview screens to watch the OUT16 EPICs output instead of the OUTMONs. 

The following screens have been committed to the userapps repo:

SHIFT SUMMARY:

Quiet shift. H1 locked for 11+hrs @ 68Mpc
LOG:

It seems that Seismon hasn't updated since the EQ near Indonesia yesterday

H1 locked and observing for 7hr20min @ 68Mpc. There were a couple of glitches and no sign of ASC pitch instability. Environment is calm and DARM looks good.
