Upon arrival I found ITF Locked in Low_Noise_3 with Horizon ~30 Mpc.

At 06:30 UTC I set ITF in Commissioning Mode.
From 06:30 to 08:46 UTC the planned Magnetic Injections in MC Building, carried out by Fiori and Cirone, went on without problems.
Upon concluded ITF unlocked and the following activities were performed:

• Planned SPRB stiffening (carried out by Vacuum crew).
• Cleaning of the new NI marionette in Cleaning Lab (carried out by M. Ciardelli, F. Gherardini and Roma1 team).
• Infrastructure checks and measurements (carried out by A. Paoli and A. Buggiani).
• SR / SPRB hardware installation (carried out by V. Dattilo, R. Passaquieti and V. Boschi). For this activity Boschi opened SPRB and SR Local Controls.
• Pillant went in atrium (LL) for a check.

All these morning activities are concluded at 09:45 UTC except for the SR / SPRB hardware installation that required the replacement of a board on SR Rack. It has been replaced and restarted only at 12:45 UTC.

ITF relocked at second attempt at 13:00 UTC with Horizon ~29 Mpc.
The planned activity on tapping test on SPRB with three new accelerometers has been postponed for tomorrow morning. People involved I. Fiori and A. Chiummo.
