ITF found in relocking and in PREPARE_SCIENCE Mode. It was not possible to relock due to the ITF unlocking at various steps of the locking acquisitions.
At 7:00 UTC I set the ITF in MAINTENANCE Mode and manually unlocked. Here a list of the activity reported to the Control Room:

- Cleaning of Scientifc Area (External firm managed by Ciardelli);
- OMC Scan/Lock (Operator);
- At 7:20 UTC, TCS Chiller Refill (Ciardelli);
- Cranes Inspection (Bazzi);
- At 8:05 UTC, Check of IMC Working Point and Position (Operator);
- TCS power adjustment (Nardecchia);
- From 8:20 UTC to 9:00 UTC, TCS Camera reference and Power checks (Operator);
- From 9:30 UTC to 11:10 UTC, INJ activity inside Laser LAb / EE Room (Spinicelli, Montanari, Melo, De Rossi);
- ACS check on DET Humidifer (external firm managed by Soldani);
- At 10:00 UTC, Final check performed by Nenci. 

At 11:10 UTC, after the INJ activity was concluded, I started the relock. 
In agreement with the expert, at 13:42 UTC we put the ITF in TROUBLESHOOTING and DOWN State to allow Montanari to go back to the NE to disconnect the accelerometers of the Suspension to revert the action performed yesterday.
ITF left unlocked.
