STATE of H1: Lock Acquisition
INCOMING OPERATOR: Oli
SHIFT SUMMARY: H1 was locked this morning until winds picked up, which kept it down through midday. Was able to get relocked this afternoon, but we just had another lockloss as I'm drafting this log.

• 14:30 - H1 relocking, up to MOVE_SPOTS
• 14:48 - Observing
• 16:51 - Lockloss - alog80354
  • Waiting for high winds to calm
• 21:09 - Observing
• 23:32 - Lockloss

LOG:

Lockloss @ 09/29 23:32UTC. Ryan S and I had been watching the FSS channels glitching but Ryan closed them literally seconds before the lockloss happened so not sure yet if it was the FSS but we think it might've been. Wind is also above 30mph and increasing so could've been that too

STATE of H1: Observing at 148Mpc
OUTGOING OPERATOR: Ryan S
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 27mph Gusts, 16mph 3min avg
    Primary useism: 0.10 μm/s
    Secondary useism: 0.15 μm/s
QUICK SUMMARY:

Observing at 150Mpc and have been Locked for 2 hours. Winds are still above 25mph but microseism is getting lower.

Since the lockloss at earlier this morning, high winds up to 40mph have made locking H1 problematic; on occasion we can lock DRMI, but rarely. Unfortunately, the forecast says these winds will stick around for most of today.

Lockloss @ 16:51 UTC - link to lockloss tool

Cause looks to me to be from high winds; gusts just hit up to 40mph and suspensions were moving right before the lockloss in a familiar way.

QUICK SUMMARY: H1 appears to have unlocked around an hour ago and is currently relocking up to INJECT_SQUEEZING. Four locklosses in total overnight; I'll start looking into them shortly.

• Winds slighty elevated, microseism still trending down
• DIAG_MAIN still reports the CO2Y laser power is low

STATE of H1: Observing at 153Mpc
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY: Observing at 155Mpc and have been Locked for 9 hours. We've been Locked my entire shift so it's been a quiet evening. Didn't get a chance to take today's calibration measurements because Virgo and Livingston stayed nice and locked.
LOG:

23:00 Observing and have been Locked for 3 hours

Closes FAMIS#26447, last checked 79824

Driftmon plots, auxiliary plots

Everything is looking good. BRSX is close-ish to the lower threshold after the latest picomotor move (80269) but looks to be staying level.

First spike on BRSX plot is pico work from September 19th (80183)
Second spike on BRSX plot is pico work from September 24th (80269)

Observing at 150Mpc and have been Locked for 7 hours now. It's been a quiet evening.

Closes FAMIS#26331, last checked 80086

Note: I'm trending them back two weeks since last week the check wasn't able to be done.

STATE of H1: Observing at 150Mpc
INCOMING OPERATOR: Oli
SHIFT SUMMARY: Mostly quiet shift with just one lockloss and an easy reacquisition. Because of the lockloss, however, we did not get the usual calibration sweeps done today.

• 14:30 - H1 relocking at LOCKING_ARMS_GREEN
• 14:55 - Alignment looks too poor for locking, starting IA
• 16:05 - H1 starts observing, fully automatic lock acquisition
• 18:58 - Lockloss - alog80345
• 20:04 - Resumed observing

H1 has now been locked and observing for 3 hours.

STATE of H1: Observing at 149Mpc

CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 7mph Gusts, 4mph 3min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.24 μm/s
QUICK SUMMARY:

Currently Observing at 155Mpc and have been Locked for 3 hours. Microseism is trending back down and winds are low.

Lockloss @ 18:58 UTC - link to lockloss tool

No obvious cause, but the lockloss tool gave this the FSS_OSCILLATION tag. This happened two minutes before I was planning on running the scheduled calibration sweeps.

QUICK SUMMARY: H1 just lost lock at 14:16 UTC, 8:34 into the lock stretch. I don't notice anything obvious as to the cause except maybe some ETMX motion immediately prior, but this doesn't look like one of the ETMX "glitches" like we've seen before. Have been trying to lock green arms for 30 minutes, so I'll start touching them up by hand.

• Wind is low, microseism is on its way down
• All other systems nominal
