Bruco coherences on 2019/04/07 at 04:00:00 UTC
Here is a Bruco scan using a LDVW default settings, with max frequency 200 Hz (plots only go up to 200 Hz, but webpage has info above 200 Hz):

https://ldas-jobs.ligo.caltech.edu/~ldvw/bruco/evan.goetz/H1-CAL-DELTAL_EXTERNAL_DQ_2019-04-07-04.00.00-180/results/

Some notable features (some different compared with Gabriele's last Bruco in late March):
- Lots of coherence 5-20 Hz with OMC-DCPD_NULL_OUT_DQ
- Second channel with lots of coherence in 5-20 Hz band and the ~35 Hz calibration lines is very frequently ASC-AS_A_RF45_Q_SUM_OUT_DQ
- Some regions with marginal coherence (~0.45) with PEM-EX_MAG_EBAY_SUSRACK_Z_DQ

Thanks Evan, 

The first two channels (NULL and AS 45 SUM) are just witnessing DARM, so they should probably be added to the excluded list for BRUCO.  

The magnetometer could be picking up the DARM signal being sent to the suspensions, but I am not sure.

INCOMING OPERATOR: Jim

SHIFT SUMMARY: Started in Observing at around 108 Mpc, dropped out briefly to troubleshoot SQZ_MANAGER issues with Sheila. At around 20:00 UTC the range dropped by about 10 Mpc and stayed low for ~2 hours. Aside from a slight wind increase and a string of small earthquakes, I’m not sure what caused it. Range has since come back up to 106 Mpc.

OPS Day Mid Shift Summary
   Busy morning.

   Lock loss just after "LSC Servo Board Split Voltage High" Message. 
   Had GRB alert while relocking the IFO 
   Rode through a mag5.7 EQ in Chile - SIESMON said to select EARTHQUAKE state. Did not change state and IFO continued to locking at NLN with no apparent issues. 

   Dropped out of Observing due to OPO SDF Diffs. ZM1 UL, LL and ZM2 UL, LL, UR, LR saturating. Looked like Squeezer was still locked. Called Keita. He cleared the Servo Filters on the SQZ_ASC Overview, relocked the SQZ_SHG, and requested SQUEEZING from the SQZ_MANAGER. SDF Diffs cleared, and the IFO is back into Observing. 

   Right now the IFO is locked in NLN with a range of 110.6Mpc. Winds are a no more than a Light Breeze. Am tracking 5 increasing Violin modes (ETM-Y mode2, mode4, mode8 & ETM-X mode6 & ITM-Y mode12). All are under 2.5 and growing slowly if at all. Will continue to monitor.

About the squeezer issues:

  • From what Keita described on the phone, I thought that the squeezer laser mode hopping could have been the problem similar to what we saw on Friday, but when Keita looked at the SHG trans diode the normalized power was something like 0.78, which is about normal, so that might not have been the problem.  
  • It sounds like the squeezer guardian reacted to an SHG lockloss by going to the LOCK_SHG state, which is the behavoir I expected after the changes made on Friday.  However, it left the beam diverter open and didn't turn off the squeezer ASC.  Keita went to the SQZ_ASC screen from the overview, turned the SQZ_WFS master switch off, and cleared the history of the ANG and POS servos, which is why the verbal alarms about the OPO model saturations stopped.  On Friday I added a decorator in SQZ_MANAGER called the OPO_checker that check for OPO locklosses and returns a jump transition.  Just now I logged in and added to that decorator lines that will turn off the SQZ_ASC, and request that the OPO guardian go to DOWN, which I will close the beam diverter.  (I would like to move the beam diverter into the SQZ_MANAGER, but won't try to do that remotely.  
  • The SHG guardian must have relocked the SHG without a problem, but the SQZ_MANAGER guardian was stalled, so it wasn't requesting the rest of the squeezer loops to relock.  I just now logged in to look at ISC_LOCK, and there is no unstall_nodes decorator on the NLN state (this is on most other states in ISC_LOCK, it prevents this kind of situation).  I have now added that decorator to the ISC_LOCK guardian in NLN.  

I haven't loaded either of these changes, since we are in observing right now, but if there is any reason to come out of observing tonight I think that it should be OK to load both of them.

Lock Loss
   15:53 (08:53) lost lock just after getting the "LSC Servo Board Split Voltage High" message. Had to do some minor hand alignment to get ALS to lock, and a quick dress up of RF18 and RF90. Rest of the relocking process completed without additional intervention.   

   Whole relocking SEISMON reported two earthquakes in Chile. A mag5.8 at 15:45:07 and a mag 5.7 at 15:45:13. USGS reported these as one event, a mag5.7 at 15:45:07. The SEISMON guidance called for EARTHQUAKE with the R3.5 wave due to arrive in approximately 600 seconds. Being in the middle of relocking, did not want to switch SEI_CONFIG modes. Saw no effect of this earthquake while relocking. 

   16:53 (09:53) Relocked and back into Observing after accepting a couple of LSC SDF Diffs.

SHIFT SUMMARY: Remained locked and in observing entire shift. One GRB alert. Noticed DIAG_MAIN notifications that the HWS code has stopped. Held lock in 'windy' through a 5.7 mag earthquake in Chili.
LOG:

Rode through a 5.7 mag earthquake in Chili originating at 10:52 UTC without changing the SEI config from 'windy'. I didn't notice the earthquake until it showed up on the BLRMS, and while the script indicated I should take the SEI config to 'earthquake', it seemed too late at that point.

13:48 UTC GRB notification (E329134). Confirmed with LLO.

Luckily, the HWS code is okay. The test in DIAG_MAIN was looking to see if H1:TCS-{}_HWS_LIVE_ACQUISITION_GPSTIME was static for longer than 5 seconds. That seems to be much too short, so I bumped it up to 60 seconds.

Good catch Patrick.
