This morning I found the itf locked in LOW_NOISE_3 state; in the first part of the shift Irene and Federico tried to do some acoustic injection in the SIB2 area, unfortunately the itf unlocked during this operation; the itf was relocked in LO_NOISE_3 state with some difficulties and the scheduled activity on 1/f3 noise started, activity in progress...
The lock acquisition was not so straight forward for the whole morning.

this morning I had to call the det on-call because of the shutters automaton get stuck in a UNSAFE_B1p state preventing to go on with the lock (#43584)
