During this afternoon shift, we had problems controlling SWEB in the correct position due to this morning's work. Around 14:00 UTC we contacted H.J. Bulten because SWEB was slightly misaligned. After several attempts, Bulten has suggested reopening the SWEB bench to check if something got stuck because he couldn't align the bench. So After checking with A. Pasqualetti (from remote), R. Gouaty, and A. Chiummo went to WEB to start the venting of SWEB and open it. 18:40 UTC As requested by A.Chiummo I blocked the green beam on the SWEB using the flip mirror. They started working with Bulten (from remote) to restore the correct functioning of the bench. ~23:10 UTC green beam not blocked anymore. They started the evacuation of the SWEB mini-tower. Recovery activities are still in progress.
