ITF found DOWN in TROUBLESHOOTING mode due to the failure of INJ system. Gosselin and Chaibi fixed it at 16:00 UTC (see dedicated OnCall intervention entry). 
While we waited for the correct values ​​of PMC transmitted power and RFC low power, I contacted the TCS expert to check the Power_DAS_IN which in the meantime had dropped out of the threshold. D. Lumaca check the powers and performed a small waveplate rotation. I centered the DMS threshold in the new value.

Relocked at 17:50 UTC after the usual cross-alignment in ACQUIRE_DRMI (SR - 2urad ty-). SCIENCE mode set.
18:37 UTC unlocked (TBC). Autoelocked at 19:29 UTC. AUTOSCIENCE.
