ITF was found in CARM_NULL_1F and PREPARE_SCIENCE mode.
Unfortunately, the increasing wind activity (fig1) prevented the lock for the first part of the shift. BAD_WEATHER mode set.
At 02:30 UTC, although the weather conditions improved, ITF unlocked however at various steps. TROUBLESHOOTING mode set.
I contacted the ISC OnCall to investigate it. Boldrini commented a line in ITF_LOCK.py which closes BS loop in full bandwidth.
ITF relocked at LN3 only at 05:32 UTC. SCIENCE Mode set at 05:34 UTC but ITF unlocked again at 05:43 UTC.
Relocking in progress...
