Operator Report - Morning shift

This morning the ITF unlocked from science at because of this earthquake:

M 7.2 - 8 km W of Atiquipa, Peru
Time: 2024-06-28 07:36:37 (UTC+02:00)
Location: 15.811°S 74.445°W
Depth: 28.0 km

its effects prevented to relock for a while, at the relock we had some issue with the automation: the squeezing didn't lock with the SQZ_MAIN metatron node trying to lock, this had a side effect on ITF_LOCK that was stuck in the LOOCKING_DARM_IR step, the problem was solved thanks to Diego and Marco removing for now the managing of SQZ_MAIN node from ITF_LOCK; meanwhile Marco worked to recover the squeezing, the ITF locked at LOW_NOISE_3, science mode started at 9:55UTC.
