Print this reportoperator reportITF found in Science mode. At 6:59 UTC the ITF unlocked because of the high wind. At 7:10 UTC I enabled the GIPC configuration for high wind condition. At 7:37 UTC the ITF was back in Science mode but it unlocked at 7:57 still because high wind.
After this unlock the wind was very high and prevented to achieve Science mode; Paolo is working trying improve the performance in this condition. We experienced also some unlocks of the squeezer which prevented to stay in LOW_NOISE_3_SQZ.
At the moment the best configuration we could reach is LOW_NOISE_3 locked with input mirrors and GIPC for high wind enabled; Hrec_Range_BNS around 43 Mpc. Due to the not standard configuration the ITF has been left in the default mode LOCKED, (see attached plot).
