H1 is currently locked for 6 hours. ITMY mode 5 with Ryan C's new setting has been damping the mode well, but looks like it is starting to ring up mode 6? Seismic activity/wind is also low, but microseism is still near the 90th percentile. Range hovering around 155 Mpc.

Very quick fill, TC temps look good but discharge_press did not get very high.

Fill did not autorun at 10:00:00, I reset its start time to 10:15:00 PST.

QUICK SUMMARY:

- H1 in observing, current lock stands at 2:15 hours

- Ground motion has since calmed down from last nights EQ, but useism is still very high - almost in the 90th percentile, holding SEI CONF in USEISM until it goes down

- CDS ok/DM PSL 102 not getting any readback

I accepted the following SDF Changes.

SHIFT SUMMARY:

7.1 mag Earthquake has tripped ITM ITMs and ETMX ISI's.
Im Still waiting for the ground motion to ring down.

STATE of H1: Observing at 129Mpc
INCOMING OPERATOR: Tony
SHIFT SUMMARY:

H1's been locked for about 20.75hrs.  The range has been somewhat decent in the last hour. 

Only other notable item is the Squeezer losing lock and dropping H1 out of OBSERVING at 0458utc & relocking 2min later.

H1's been locked 16.75hrs and the rougher range sadly continues.

QUICK SUMMARY:

The mysterious range fuzziness continues with range variations from 120-155Mpc since 11pm PST 17hrs ago (vs our usual 155-165Mpc).

Also got the note from RyanC, for next lockloss to:  Reload ISC LOCK & VIOLIN_DAMPING nodes.

STATE of H1: Observing at 148Mpc
INCOMING OPERATOR: Corey
SHIFT SUMMARY:

Low frequency noise has been a little elevated during this lock and the range is still a bit fuzzy, not totally sure whats causing this.

ITMY modes5/6 are slowly damping down with a gain of +0.02 (nominal is set to -0.02), I set the gain of ITMY5 to 0 in lscparams so ISC_LOCK and the VIOLIN_DAMPING guardians should be reloaded at the next opportunity.

We dropped out of observing briefly for Naoki to adjust SQZing from 20:52UTC till 20:54. We've been locked for 9:20

The H1 range has started to get fuzzy? starting in the 2nd half of yesterdays lock (7 hours into it), Around 07:00UTC (11pm local PST) to be precise and has continued to act this way during todays lock which was automated and locked at 11:16UTC this morning. There was what looked like a glitch/saturation on the SQZ DCPDs right when the range drop increases started but there were no callouts on verbal.

Since I've changed the SEI state back to WINDY the range decreases/drops seem less severe? But its only been like 40 minutes. I don't really see anything really changing on the SQZ scopes looking around 07:00UTC and our current lock. I don't see any drifting or anything weird on the ZMs and FC2 suspensions as well.

CURRENT ENVIRONMENT:
    SEI_ENV state: SEISMON_ALERT
    Wind: 7mph Gusts, 5mph 5min avg
    Primary useism: 0.04 μm/s
    Secondary useism: 0.26 μm/s
QUICK SUMMARY:

• WE've been locked for 4:40, in observing since 11:19UTC
• Microseism is still nicely trending down, winds picking up a bit, EQ incoming from Bolivia
• Our range has been a little lower this current lock, SQZ looks good, maybe its from the wind/SEI configuration? Since were still in a microseism SEI config
  • If we drop out of Observing I'll change the SEI config back to WINDY as the forecast has the wind continueing today into tomorrow
• ITMY5/6 continutes to be the largest violins, just under 10^-16
