Monday Ops Day shift start

TITLE: 11/11 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 161Mpc
OUTGOING OPERATOR: Ryan C
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 6mph Gusts, 4mph 3min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.33 μm/s
QUICK SUMMARY:

Ryan C was called last night at 9:24 UTC.
When I walked in Sheila was in the Team speak chat, so maybe she was helping out with getting it locked first thing in the morning. 

NLN reached at 15:37  UTC
Observing reached at 15 :40 UTC


 

H1 OPS OWL assistance

H1 called for assistance at 09:29 UTC after the initial alignment timer expired from the IMC unlocking an not relocking, we were in PREP_FOR_SRY. I took us to down and the IMC locked and I then went back into locking where DRMI locked very quickly and looked pretty decent.

OPS Eve Shift Summary

TITLE: 11/11 Eve Shift: 0030-0600 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Aligning
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY:

IFO is LOCKING at CHECK_AS_SHUTTERS

Overall a smooth shift where we were locked for two thirds of the shift until the PSL glitch most likely took us down. Since then, the glitch has been happening without much gap for relocking. We've had gaps of 20 or so mins without glitching but that's been the maximum so far since LL. Lockloss alog 81181.

Other than that, we dropped out of OBSERVING very briefly due to a TCSY CO2 Laser SDF diff that fixed itself.

LOG:

None

H1 ISI CPS Sensor Noise Spectra Check - Weekly FAMIS 26016

Closes FAMIS 26016. Last checked in alog 80912. 

Changes from last check:

• HAM8 CPS slightly noisier
• IY ST1 CPSINF2 channel noisy
• BS ST2 CPSINF H1 has a new bump 1-3Hz
• EY ST1 less noisy

Lockloss 03:42 UTC

Lockloss seemingly PSL caused judging from IMC and ASC-A signals losing lock within 10ms (attached). About a 700ms after the glitching started, we lost lock. Interestingly, IMC is not glitching for minutes post-LL as it usually does, with IMC locking and staying locked in the new acquisition.

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

IFO is LOCKING in LOCKING_ARMS_GREEN

Shift has been very smooth with a behaving IFO. I was locked the entire time up until now, where an IMC glitch took us down most likely (alog 81170)

Also took a thermalized IFO calibration sweep with the temp/new ini file. Alog 81169.

LOG:

None

 

Lockloss 03:19 UTC

Lockloss seemingly PSL/FSS related. Glitching in FSS started around 1s Lockloss. It's still glitching right now.

Friday Ops Day shift End

STATE of H1: Calibration
INCOMING OPERATOR: Ibrahim
SHIFT SUMMARY:
The morning was plagued with IMC Fault issues alog . 

After simply holding ISC_LOCK in  DOWN and holding IMC in LOCKED [ Specifically  to Not be in "ISS_ON " ] to wait for the IMC to be calm before starting to relock. Then wait again for a 5.8M EQ from Panama, I was able to get a lock all the way to Observing.

I was able to pass a locked IFO to Ibrahim.
