ITF found in Science Mode, unfortunately it unlocked at 7:00 UTC and I started to have problems to reach again the Science Mode collecting several unlock (at different nodes) during the acquisition. Finally the Science Mode has been achieved again at 8:18 UTC. The Commissionig activities started as planned at 9:34 UTC, moreover, before start the acoustic injections in CEB, Antonio P. e Marco C. performed a check at the NE building in order to find the origin of the excess of noise reported on the entry #48809, they discovered that the air flux in the cleaning room has been remained switched ON since the last maintenance, standard working condition restored (plot n1 attached).
