The commissioning activities CO2 lasers activities and scattered light on EIB were  were concluded at 17:00 UTC.

After an initial alignment of the cavities we were able to reach LOCKED_RECOMBINED; in this state we had a problem with the node DET_MAIN which was stuck in the state CHECK_SHUTTER_CLOSED preventing to go ahead with the lock acquisition. I tried to restore the situation by putting the node in INIT, reloading the code and also restarting the node; unfortunately these actions did not solve the problem. At 18:20 UTC I contacted the on-call who started working from remote.

At present the problem is still unsolved; Bas, Romain and Michal are working from remote together with Marco, Enzo and Michele in Control room.
