TITLE: 10/26 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Wind
OUTGOING OPERATOR: Tony
CURRENT ENVIRONMENT:
SEI_ENV state: USEISM
Wind: 31mph Gusts, 23mph 3min avg
Primary useism: 0.05 μm/s
Secondary useism: 0.52 μm/s
QUICK SUMMARY: H1 has been down since 07:09 UTC and struggled to lock overnight due to high winds. Gusts are still high this morning, but I'll try to run H1 through an initial alignment and locking to see how far it gets.
H1 back to observing at 17:23 UTC
Ran an initial alignment then had H1 relock on its own. One lockloss during TRANSITION_FROM_ETMX, which I'm blaming on a combination of wind and microseism, but H1 made it to low noise on the second try fully automatically. I soon saw the 1 Hz ASC ringup after reaching NLN, so I tried raising the CSOFT_P gain to 30, but didn't see the ringup stop. Out of an abundance of caution I transitioned to high-gain ASC, which did stop the ringup, so a few minutes later I set the CSOFT_P gain back to 25.
I also had to run the switch_nom_sqz_states script for observing with squeezing to fix the nominal states of the SQZ Guardians since it looks like Tony must have run it at some point overnight.
