Virgo Logbook

This morning I found only the north arm locked (#41771); about the west there was a problem with the west end building air conditioning: the system stopped to work on Saturday night at 00:40utc and it has been restarted this morning at 5:45utc (see plot), this caused some problem with the vertical position of the west-end suspensions (both tower and minitower suspensions); so in the first part of the shift Paolo and Alessandro (from remote) worked to recover the good working condition of the suspension then the itf has been relocked up to LOW_NOISE_3 state and the foreseen activity started.
The suspension's thermal transient is still ongoing, probably some other adjustment of the suspension will be needed...

-sbe
to allow the recovery of SWEB minitower control at ~6:30utc I switched on the SWEB motor crate and it is still ON.

-inf
reset of the eeroom eurotherm box at ~7:42utc because of missing data.

-vpm
SDB2_PowerSupply restarted at 6:15utc because of crashed
SPRB_PowerSupply & SWEBPowerSupply restarted at 6:15utc because of crashed
ITF_LOCK restarted at 6:19utc because of red from vpm side even if it was still running and visible from metatron client.
