ITF found in DOWN state and in EARTHQUAKE Mode (M 5.9, 11:57 UTC, 164 km SE of Vilyuchinsk, Russia). From 13:24 UTC it was possible to relock, ITF back in Science mode from 14:07 UTC.
At 17:19 UTC the temperature of the Neovan head suddenly increased from 28 to 36 degrees, triggering its safety. To restore the system De Rossi went to the Laser lab and from 18:00 UTC it was possible to relock again.
ITF back in Science Mode from 18:46 UTC, it unlocked again at 19:17 UTC due to the influence of an earthquake (M 6.1, 18:20 UTC, 219 km ESE of Severo-Kuril’sk, Russia).

The chiller was givinig "flow error". Indeed it seems that the flow stopped at first (something blocking it?), and then the temperature started to increase (plot 1). I just stopped and restarted a few times the chiller, and unplugged both the outlet and inlet pipes, in order to verify that the water was flowing. I did not try to reverse the flow because the chiller restarted before doing this last test.
The system seems to be returned at its nominal value (plot 2).
