ITF found in Science, BNS Range ~55Mpc.
- 08:35 - 09:14UTC, Troubleshooting mode to allow S.Andreazzoli to enter in MC building to check the situation about the air conditioning
- 08:48UTC, ITF unlocked, probably due to the increment in wind activity
- 09:38UTC, Bad Weather mode due to the difficulties in relock the ITF caused by the wind (09:47 - 10:07UTC exit from bad weather beacause I forgot to stop ITF_CONDITIONS node)
HVAC
At 08:25UTC, S.Andreazzoli came on site to check the status of the MC's air conditioning system
After the inspection, He reported that the system's operation showed no anomalies. The saturaion of correction signals is likely due to machine settings, further investigations will be done tomorrow, during working hours.
Regarding the building's temperature, out of the seven probes present, only two show a considerable increment, its positions should be check to determine the cause (1st plot).
ALS
The weather comprise WEB ALS system.
The green beam at WEB switched off after any unlocks, triggering the fault state of the corresponding metatron node. In this state, to proceed in lock acquisition, it requires a manual intervention to init the node.
I tried to check the input power of the IR, but without the SOA on path, the PD is not able the read the power (2nd plot).
I called the expert which confirmed it could be correlated with the weather conditions.
