TITLE: 05/21 Eve Shift: 2300-0800 UTC (1600-0100 PST), all times posted in UTC
STATE of H1: Observing at 141Mpc
INCOMING OPERATOR: Corey
SHIFT SUMMARY:
Due to 2 backto back locklosses that both happened at LOWNOISE_LENGTH_CONTROL, after 2 sec in that state, I decided to stop in the state directly before and walk through Line by Line to see if there was a particular line in the code that was causing a lockloss. Each line was ran and no lockloss happened. We made it back to OBSERVING at 7:09 UTC.
The wind was elevated, at the time of both locklosses so perhaps it was the wind or the incoming 5.7M earthquake , Plots attached. Perhaps a coinicidence? IDK.
ISC_LOCK.py is still the previous version the latest version is this one: ISC_LOCK.py_20may2024
I do beleive I made a change in the Current copy of ISC_LOCK.py but that change should be discarded in favor of ISC_LOCK.py_20may2024
