H1 has been locked 15+ hours, and I ran some dataviewer trends looking at 2 hours, and found some optic alignment changes that I think are interesting, and some that might show up in DARM.

STATE of H1: Observing at 69.4542Mpc
INCOMING OPERATOR: Cheryl
SHIFT SUMMARY: Quiet Shift
LOG:
Nothing to report, Corey had the IFO locked when I got here, it's still locked as I'm leaving.
Bubba and Chris found our water leak! Overnight the potable water tank level held steady at 4.3 feet after the warehouse water was shut off. Next comes the digging.

STATE of H1: Earthquake
INCOMING OPERATOR: Jim
SHIFT SUMMARY:
Once I sat down to H1, able to get to NLN with no issues. Have had a handful of EYSaturations during this lock. Seismic trends are steady & winds are getting quiet.
LOG:
Forgot to note that while handing off to Jim last night, that he did have to make some quick adjustments to the MODE28 (in the 8-9utc hour).
Had a pair of EQs reported on Terramon within 8min of each other and both near the Solomon Islands
Since we've been having constant Dust Alarms for the PSL Enclosure (#101), looked into trends over the last 2 months (looked at #101, wind, and some FMCS/HVAC channels).
Since the levels as they currently are I wanted to inch them up a little (by x2). This will help to reduce the constant alarms we get and prevent us from ignoring them. But it is a small enough bump that we'll still get them when we are at higher levels. Since there has been no change post-cleaning on 12/5, Jeff should investigate the air filtration system for the PSL. Do we have requirements for cleanliness levels for the PSL Enclosure?
Alarm Setting Changes
0.3um: MINOR: 70->140 & MAJOR: 100->200
o.5um: MINOR: 70->140 & MAJOR: 100->200
Locked for 3+hrs. Rode through a couple of Solomon Island rumblers (L1 went down). Also ran an A2L an hour or so after this lock (right as L1 was joining us). H1 started off at a high range (almost 80Mpc, slowly dropped around 65Mpc & is back up to around 73Mpc. Smooth saling.
As soon as H1 went up, L1 went down.
EQ levels subsided so immediately proceeded with locking (only hitch was a low X-arm for ALS & this was remedied with a slight TMSx tweek). Made it to NLN with no issues.
I saw we had quite a few Test Points open on the CDS Overview (some were 20+ for some PEM front ends). I went about running a TP Clear on all of them (except H1CALEX which had 1). In case you were interested the frontends I did a TP Clear on, had the following DCUIDs: 24, 30, 31, 75, 50, 54, 55, 60, 98, 99, 80, 118, 10, 19, 121, 88, 89, 91, & 84.
Shortly thereafter, I hammered down the MODE28 PI before it got raucous (phase sign flip).
Range is hovering around 75Mpc.
Transitioned OBSERVATORY_MODE from EARTHQUAKE to OBSERVING.
Looking at Violin Mode peaks on DARM, we have:

STATE of H1: Earthquake
OUTGOING OPERATOR: Jeff
CURRENT ENVIRONMENT:
Wind: 10mph Gusts, 6mph 5min avg
Primary useism: 0.04 μm/s
Secondary useism: 0.34 μm/s
QUICK SUMMARY:
While double-checking locked doors (and front door knob also locked), I went ahead and turned OFF lights for weekend conditions, this included the Mechanical Room & Mass Storage Room.
Corey suggested looking at DIAG_SDF log, and there is activity that coincides with H1 going out of Observe:
19:19:45UTC - H1 out of Observe, and DIAG_SDF shows:
Now, how do I know what "USERMSG 0: DIFFS: sysecaty1plc2: 1" is?
Keita's alog 32134 - instructions on how to look for channels that changed
My bad - investigating - looked at SDF - kicked H1 out of Observe:
DIAG_SDF log:
From Keita:
I took
/opt/rtcds/lho/h1/target/h1sysecaty1plc2sdf/h1sysecaty1plc2sdfepics/OBSERVE.snap
and stripped unnecessary information, split into 20 line chunks and
put them here:
/ligo/home/keita.kawabe/LockLoss/SDFERRORS/h1sysecaty1plc2
Could you again run the lockloss tool by
for ii in ecaty1plc2*; do lockloss -c ${ii} plot -w '[-10,10]' gpstime; done
This morning (Monday Dec 12) I ran the lockloss script and I can see that H1:ALS-Y_FIBR_LOCK_TEMPERATURECOMTROLS_ON was flipping (see attached, second column from the left). Other things like LASER_HEAD_CRYSTALFREQUENCY, CRYSTALTEMPERATURE and VCO_TUNEOFS were also changing but these were not monitored.
Anyway, it's strange that this was not found when Cheryl and Corey ran lockloss tool. Maybe NDS2 was misbehaving?
Just to make sure, what I did is:
cd /ligo/home/keita.kawabe/LockLoss/SDFERRORS/h1sysecaty1plc2
for ii in ecaty1plc2_a*; do lockloss -c ${ii} plot -w '[-10, 10]' 1165432802; done
