The ITF unlocked at 20:07 LT for no obvious reasons (~24h of Science Mode, ~40h of locking).
After the unlock the WE LC were opened by the guardian and the relock took a bit of time because I had to close and damp the WE loop and to realign the mirrors.
Finally the ITF was relocked without problems and at ~21:15 LT it was again in Science Mode.
Before the unlock the Horizon was around 10Mpc with many drops; no evident explanation for the drop occurred at ~18:12 LT. After the relock the horizon was a bit lower but it is slowly increasing... (see plot 1 and plot2).
Vacuum
