MID-SHIFT SUMMARY: Locked at 80Mpc+. A few ETMY glitches. 45MhzRFAM is nice and normal. Winds are still calm. We rode out an earthquake from the Burma are and are currently facing a possible 1µm/s wave from an El Salvadoran quake. THere was an FMCS alarm that I logged and sent an e-mail to Bubba about. It looks as if there was a change made to the temp in the CS yesterday at some point around 12:00UTC and the alarm threshold for this is set rather tightly. Livingston remains down since 09:46UTC.

Critical Alarm at 11:15 for H0:FMC-CS_LVEA_REHEAT_2B_DEGF. Attached trend show past 24 hours for this channel. I'm not entirely sure how long this alarm has been present. Also attached is a screenshot of the current CS FMCS. I noticed the aLog regarding the temp increase at Y end . I have not yet found one regarding the corner station.

09:10UTC. IFO is locked and in nominal observing state. Terramon is reporting and incoming R-Wave of .5µm/s in ≈15min. Livingston didn't answer the hail. I'll try again.

TITLE: 11/26 [EVE Shift]: 0:00-8:00 UTC 

STATE Of H1: Observing @ ~ 75 MPc.
SHIFT SUMMARY: Lost lock at 5:30 UTC, initial alignment was tough, CARM reduction is rough
SUPPORT: 
ACTIVITY LOG:

5:30 Lockloss, I let Guardian try to relock, but DRMI cavity flashes are poor and worse when I try to get PRMI, so I start initial alignment. X-arm IR is difficult, refuses to lock and MC drops lock frequently. After Input align, the rest goes ok. Relocking goes pretty average. CARM reduction was a sore point, as usual.
8:00 NLN right as Ed arrives

STATE Of H1: Observing

OUTGOING OPERATOR: Jim

QUICK SUMMARY: IFO is locked at NLN and Observing @ 80 Mpc. Seismic environment is quiet. Wind is quiet. Looking good to me.

Another quiet night. Observing at ~80 Mpc, wind is low, microseism is low. We rode out one small earthquake about 1hr45mins ago, a 4.7 in Japan, supposedly.

At Andy's request, I have compiled a list of psinject start/stop times that occurred
during observing mode, based on the times of starts, stops and errors reported in
the psinject log files on h1hwinj1. For inserting segments in the database, I have
substracted 1 second from the start time and added 1 second to the end time.
I have also verified that I can see a large glitch in H1:CAL-INJ_HARDWARE_OUT_DQ
at these times:

The tcl script used to find these times is attached, along

STATE Of H1: Observing @ ~ 75 MPc.
SHIFT SUMMARY: Lost lock for unknown cause. Relocked fairly easily. Observing since. Bubba came in to increase the temperature at end Y. Winds have calmed back down to between ~ 0 and 5 mph. Earthquake band has dropped back down to between 0.01 and 0.03 um/s.
SUPPORT: Bubba
INCOMING OPERATOR: Jim W.

Still in observing at ~ 79 MPc. The winds have started to come up and are between ~ 0 and 20 mph. The 0.03 - 0.1 Hz (earthquake) seismic band has increased at end X and end Y to between ~ 0.02 and 0.1 um/s. The 0.1 - 0.3 (microseism) band may be starting to slightly decrease.

SUS ETMY saturations continue. Have not seen signs of RF45 noise.

Bubba came in to increase the temperature at end Y.

ISI blends are on Quite_90.
The continuous wave injection appears to be running on PCALX (The 'Cont. Wave Inj Signal' box is purple on the CAL_PINJX_CONTROL medm).
I accepted the SDF difference for the SUS ITMY damping filter gain. Nutsinee told me I would have to because guardian would reset the change she made alog 23734. See attached snapshot.
There is one testpoint open on H1LSC.

Relocking sequence:

Moved ETMY in Pitch to lock ALS.
No DRMI lock after 12 min. Attempting to lock PRMI.
Locked on PRMI.
Adjusted both BS and PRM in Pitch and Yaw.
Requested DRMI_LOCKED.
Transition failed.
Locked on DRMI 1F after ~ 5 min.
Waited on DRMI_LOCKED for ASC loops to converge for ~ 3 min.
Stopped at ENGAGE_ASC_PART3 to wait for ASC loops to converge for ~ 10 min.
Engaged ISS second loop by hand.
NLN
PSL ISS diffracted power went to ~ 11% but eventually came back down to ~ 8%.

We checked a number of short, unexplained glitches (blip glitches) to see if they are due to missed samples between OMC-DCPD_SUM and LSC-DARM_IN1 or between LSC-DARM_OUT and SUS-ETMY (as in LLO aLOG 23058 ). No mismatches were found in either of them.

The times of those glitches were obtained from the PyCBC searches:
1127959777.60
1128085613.28
1128221842.47
1128264648.20
1128078450.31
1128264485.84
1128279893.94
1130132047.202
1129748691.016
1130156793.541
1131357114.918
1130768253.356

Cause unclear. Nothing on seismic DTT.

From trending H1:FEC-117_GDS_MON_0 (the channel on the OPS overview) it looks like it changed around 21:35 UTC on Nov. 24. Is this because it was switched to PCAL X and the medm needs to be updated to use a different channel? alog 23701

I have increased the heat at both end stations, End-X by 1.5Ma and End-Y by 1Ma. I have also increased the heat in zones 2B and 3A, each by 1 stage in the LVEA. I will continue to monitor all of these changes.
