• 1920 LVEA transitioned to HAZARD (corey)
• 1933 DAQ restart (Dave)
  • One of the models restarted was ASC IMC.  
  • Unfortunately, the IMC was in the LOCKED state at this time, so after the model restart the IMC came back misaligned.  Top Masses for MC1/2/3 were restored (by Jeff/Oli/corey) by looking at their M1_DAMP_[X]_INMON and steering the mirrors back to their values before the model/daq restart.  Still had issues with getting IMC to lock.  Then Jeff tweaked the PSL IMC PZT mirror in pitch a little and then IMC WFS took over from there to lock and align the IMC.  So for next time, make sure to take the IMC_LOCK guardian node to OFFLINE.
• 1935 Green X Camera work (elenna, fil)
• 2025-2126 Transition LVEA back to SAFE + did an LVEA Sweep (but as I was finishing up, a few items came up):
  1. SQZ team needed to head back out for more SQZ work.
  2. A new Power Supply was discovered to be failing in the CER (the IO Chassis supply for H1SEI23).  See Marc's alog85475.  So this one (3rd of the day) coincided with a HAM2 ISI WD-tripping (or going OFFLINE) at 2101utc.  This appears to have led to a possible input pointing issue, because during an Initial Alignment, H1 was stuck waiting to lock the red X-arm during INPUT_ALIGN.  To get the X-arm to lock, Elenna needed to move a mirror (either PR2 or IM4) quite a bit.  Continued with this alignment and went for locking. H1 made it to OMC_Whitening, BUT it was going to stay here for quite a while---the violins were really rung up from Maintenance activities (notified Rahul)....we eventually had a lockloss.  This where H1 ended up at the end of the shift.  Opting to lock again with the current alignment.

STATE of H1: Preventive Maintenance
OUTGOING OPERATOR: Corey
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 18mph Gusts, 11mph 3min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.05 μm/s
QUICK SUMMARY: H1 has just relocked following the maintenance period today, but currently waiting in OMC_WHITENING to damp some very rung-up violin modes. Meanwhile, Elenna is running jitter noise injections. I'm also aware of the OPO crystal move from today, so I'll be watching SQZ performance this evening and will adjust the temperature if need be.

• Wind and microseism low
• All other systems nominal

STATE of H1: Observing at 146Mpc
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY:

IFO is in NLN and OBSERVING since 19:42 UTC (9 hr lock!)

An extremely calm shift in which the circumstancial lock-killing culprits of the world evidently and collectively decided to take a nap. In other words, there have been no earthquakes, the secondary microseism is as low as can be, wind is under 10mph, no SQZ locklosses, no ETM LLs.

The only thing worth commenting on is that the SQZ angle is probably not ideal but according to past instructions from Sheila, we shouldn't go to comissioning if there are other IFOs observing. Since this was the case the entire shift, I did not drop out to try and optimize SQZ so this will have to wait till tomorrow/another lock.

Ryan C reports a very calm shift with the only comment that he had to run 2x initial alignments. I had to do this also a few days ago despite good DRMI flashes.

SHIFT SUMMARY:

IFO is in NLN and OBSERVING as of 00:40 UTC (4 hr lock)

A very calm shift in which we were able to lock fully automatically following an ETM Glitch Lockloss at the beginning of the shift (alog 85413). Otherwise, our range has remained mostly steady.

We also surtvived a 4.6 EQ from Northern California (and 2 of its similar aftershocks),.

STATE of H1: Lock Acquisition
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY:

IFO is in ACQUIRE_DRMI_1F and LOCKING

Overall a very calm shift in which we were locked for the majority of it until the ETM glitch (lockloss alog 85402) killed the 8 hour lock.

Relocking was time consuming since the alignment was terrible and we have the 30 min wait before we can do an initial alignment. After I ran a fully auto inital alignment, locking went quickly until we lost lock at LOWNOISE_ASC (522). This also happened yesterday. Just like yesterday, the wind was hovering around 25mph with the primary microseism on the rise. Just like yesterday, there was an earthquake coming through. While I think we could have rode the EQ out and that the wind conditions weren't too bad, I believe that either this state might be a tad more susceptible to such noise or there's a controls issue. (or the same thing happened twice in the same way and will only happen twice). I will investigate tomorrow during shift.

Either way, we lost lock from DRMI but flashes looked good and I think (knock on SSTL) guardian will be able to get into OBSERVING on its own.

On the bright side, we rode through a 6.1 EQ from the phillippines though I did intervene to turn EQ mode on manually since the bulk of the ground motion was starting but the automation hadn't turned it on yet (judging from how much the ISC had to move to keep IFO still).

QUICK SUMMARY:

IFO is in NLN (since 18:36 UTC) and OBSERVING since 19:33 UTC (4.5 hr lock)

An hour was spent comissioning to fix SQZ ASC, which now runs deeper into thermalization after NLN.

Otherwise, just planning to continue observing as long as possible!

SHIFT SUMMARY:

IFO is in NLN and OBSERVING as of 04:13 UTC

Quite the frustrating shift in which I encountered:

• Issue ALSX Crystal Freq -- - has been happening for at least a week now. Fix: Toggle the ALSX PLL on/off but this barely works if at all. Eventually, it cleared on its own after about 45 minutes of low hope.
• Issue: 2 Lockloss-causing 3.0 EQs in south Oregon. Fix: Increase luck.
• Issue: SQZ_ASC issues and inability to lock SQZ LO. Fix: With Camilla, saw that SQZ ASC was driving ZM4/6 cts to the 900s so reset history and edited SQZ params to disable SQZ FC until tomorrow. After resetting the history, SQZFC worked just fine. This issue caused us to drop from OBSERVING from 04:13 to 04:53 UTC. (accepted SDF below)
• Issue: DRMI Locking: Truly no clue if it is an amalgamation of bad aligment, winds from 20-30mph and high microseiem (primary) or just bad luck. The flashes for both PRMI and DRMI both times were more than sufficient to lock DRMI yet we waited in these states for more than a cumulative hour just waiting for lock. I had to run 2 initial alignments after I could not lock on the first auto one for over 2 hrs. I ran a second manual initial alignment and this seemed to work. Then, we lost lock due to an ADS_EXCURSION (according to Lockloss Tool) and the DRMI issues were back. After repeating MICH, PRMI and DRMI multiple times, finally PRMI caught and I was able to lock (and eat). Lock trouble details about this in alog 85377. Fix: Manual Initial Alignment (apparently)

INCOMING OPERATOR: TJ
SHIFT SUMMARY: H1 lost lock due to one or more earthquakes this evening and is still working on relocking. Despite everything running smoothly and automatically on the way back up, there was a lockloss for some reason during MAX_POWER as I type this, so H1 will be trying again on its own.

  • 03:56 - Starting initial alignment

QUICK SUMMARY:

H1's been locked for almost 12.5hrs  and it looks like we had a brief outage from Observing due to the SQZ dropping us out just before 1300utc/6amPDT, but SQZ MANAGER and H1 got back to OBSERVING automatically within a 5min (coincidentally, this improved the H1 Range [which had been drifting down below 150Mpc] getting it back to above 150Mpc.

Environmentally, we are doing well; useism had been above the 50th percentile and has been drifting down from this for the last 10hrs.  Winds are low and it is a cloudy and cool morning.
