We tried to recover the alignment of the NI using as a reference the camera image on B4 and the DC power signal. We explored several position both of NI and WI, by moving the local controls (and PR and BS for checks). We maybe were able to find the main beam on B4 cam. Tomorrow we will continue.
Today we moved both BS and WI using the old references of the optical levers, and we could find also the WI-reflected beam on the B4 camera. Both reflected beams are now visible (the third one is the second reflection of the NI one).
