ITF found in Down State and Upgrading Mode, North Arm Cavity locked.
The shift was dedicated to the recovery of the West Arm cavitiy after the WE intervention, carried out by Casanueva, Bersanetti, De Rossi, Boldrini with the remote support of Was.
After various attempts to realign the cavity, from around 21:15 UTC I started to use the WE Snail to see flashes on B8. I have left it running until 21:15 UTC, but unfortunately I wasn't able to spot any flashes on the photodiode. After stopping the movements, I returned WE MAR TX and TY to its initial starting point for the procedure (TX: 31, TY: -564).
North Arm Cavity left locked.
Figure 1 The beam arrived several times during the snail on the markers of the WI mirror, with spikes of power on the areas of the markers (looking at the video images of the camera it is clear that these are the markers)
Figure 2 Zooms in a few of the peaks. The right areas seems to be for WE TY at around 0, and WE TX at around 150
