ITF found in LOW_NOISE_3 and in Science Mode. It unlocked at 19:51 UTC and, as requested by Nardecchia via mail, I checked the value of TCS_WI_CO2_POWER_CH_PICKOFF, which was above threshold. I contacted the TCS Oncall (Lumaca) who fixed the issue, but also noticed that at 19:40 UTC, around 10 minutes before the unlock, the values of TCS_NI_CO2_PWROUT and TCS_NI_CO2_POWER_CH_PICKOFF suddenly decreased (see attached plots). At 21:00 UTC I went to the TCS Room to find a possible cause of the issue, but no clear culprit were identified.
Investigation and relock in progress.
