Operator Report
The relock was a bit difficult with fails in almost all the steps of the lock acquisition, here the calibration at LOW_NOISE_3:

- 00:47UTC: Measurement of actuators response for NI,WI mirrors (CALIBRATED_DF_INtoEND_LN);
- 01:41UTC: Measurement of actuators response for NE,WE actuators and NI,WI,BS marionettes (CALIBRATED_DF_PCAL);
- 02:14UTC: Measurement of checkHrec, NE,WE,BS,PR,SR optical responses, and sensitivity (CALIBRATED_DF_SENSITIVITY);

it was not possible to engage the squeezing with the SQZ_MAIN metatron node stuck in SQZ_LOCKING_NO_FC state (experts informed by mail), science mode started at 3:00UTC


- guard tours (UTC):
4:14 --> 4:44

After the tuning of the source performed by Henning yesterday morning, the SQZ source was in a state in which was not possibile to engage it directly using automation. I locked it by hand now it is possible to inject SQZ again.

Next week I will add two lines in the automation to overcame this problemĀ
