During the early morning BKR used a diffrent trajectory at LINAC to continue lasing, altough with poor performance.

A Desy expert was found (voluntary basis) to made a second ZZ in the morning between 10:30 and 12:30 which fixed the faulty relay for the quadrupole/cold magnet quench system.

Beam was restored to FXE, HED and SQS instruments at ~14:00, including the change of photon energies in SA1 and SA2 as well as pointing corrections and necessary fine tuning.
