The planned commissioning activity started around 7:00 UTC.

Unfurtunately the ISYS was not collaborative as we suffered of many fast unlocks (see attached plot) which prevented the smooth running of the activity.

At around 9:00 UTC we contacted the ISYS on-call, see On-call intervention.

Other activities:

- TCS: CO2 guardian system ON, all the related flags have been unshelved on DMS under request of Ilaria;

- SVS: Optimization of mode matching on EQB1 for SQZ measurement (Sorrentino, Garaventa)

- SIN: PSD installation on SQB2 (Polini, Vardaro, ?)
