In this afternoon shift science mode stopped from 15:35UTC to 18:30UTC for daily calibration and commissioning (RIN coupling vs MICH and PRCL offsets), the ITF unlocked at 15:58UTC with a DOWN command from my ITF_LOCK client, I missclicked on the metatron client instead to set DOWN the CALI node I did it for ITF_LOCK without realizing it; the relock was a bit longer with three fails two locking at CARM_NULL_1F and one meanwhile locking the OMC (#64183).

from 14:50UTC the MC building air conditioning started to malfunction with a little increasing of the hall temperature (see plot); experts aware of the problem, an extraordinary maintenance of the system is foreseen for tomorrow.

The ITF kept the lock all the shift, from 5:00UTC the sensitivity started to worsening and the BNS range went down to 35Mpc, this is because of at the relock the end green beams was not flipped out, I did it by hand to recover the standard sensitivity, science mode stopped from 5:13UTC to 5:17UTC.

In this afternoon shift science mode stopped from 16:00UTC to 19:02UTC for daily calibration and commissioning (PRCL offset scan and ISC noise injections) and for troubleshooting from 14:45UTC to 14:48UTC to solve the problem with Hrec; the ITF unlocked during the commissioning and it relocked at the first attempt.

from 14:07UTC to 14:45UTC we had a strange behavior of Hrec with the range going up and down randomly and the sensitivity too, it was because of a test done by Alain on a test version of Hrec that by mistake was writing in a wrong shared memory.
Offline Hrec test setup
While installing an offline Hrec test setup in the CascinaTest Cm domain, this afternoon I duplicated the Hrec configuration, updating the FD_IN parameters but forgotten to update the FDOUT ones .As consequence, when I started this offline server on the same host where the online Hrec server is running (olserver52), there were some troubles with the Hrec online data .I didn’t realize it was creating problems as I was working with offline data and in the CascinaTest Cm domain. When I realized this , I contacted the Control room and I fxed the issue .
This issue started at 2024-04-26-14h08m02-UTC and was fixed at 2024-04-26-14h40m34-UTC

Sub-system reportsDAQ
at around 8:33UTC the VPM stopped to work and became unreachable over the net, restarted thanks to Emmanuel (#64088).
The shift was dedicated to maintenance, here a list of the activity reported to the control room:
- standard Vacuum Refill from 6:00UTC to 10:00UTC (VAC Team);
- cleaning of central and mod cleaner buildings (Gargiulo with external firm: from 6:00UTC to 10:00UTC);
- HVAC: weekly checks and extraordinary maintenance fo the DET area UTA (Soldani 6:15UTC to 10:00UTC);
- SUSP: NE local control maintenance (Majorana from 7:55UTC to 9:40UTC);
- INJ: check of IMC working point and position from 6:22UTC to 6:32UTC;
- DET: OMC shutter driver replacement (#64070);
OMC Lock in single bounce configuration from 6:49UTC to 6:55UTC;
OMC scan in single bounce configuration from 7:03UTC to 7:24UTC
- TCS: chiller check and refill (Gargiulo 6:45UTC);
thermal camera reference from 8:13UTC;
power checks and power adjustment done by Ilaria;
all the activity completed at 10:00UTC, ITF relocked at the first attempt; the work on detection area air conditioning system created a big transient on the temperature (see plot) it prevented to use the squeezing that is suffering of the change of temperature (QNR on-call informed), for the time being we go on without the squeezing injected.

This afternoon shift was dedicated to commissioning: MIR/MAR reallocation, the work was carried out by Diego, Manuel and Paolo; during the afternoon we collected several fails in LOCKING_DC_READOUT state while opening the B1 PD1 and PD2 photodiode shutters, we succeeded to pass this state only two times, in the evening we called Victor (DET on-call) to investigate this issue, investigation on locking troubles in progress...
