Day operations

Mounting

• Mounted the unit on the telescope
  • REMAIND: formal request to LBTO about mount the Swagelock of the telescope cooling lines on the swing-arm interface
• Removed the mirror cover (M2 retracted)
• gap has no contamination: TSS enabled (switch in the swing-arm cabinet)
• at zenith tested set_and_flat: OK

Night

• Dome opened at about 01:40UT
• No mirror cover: Software started to handle TSS (checked communication between AdSec Arbitrator and AOS for windspeed data)
• M2 is retracted: no setting of the shell is allowed during the night
• Temperature cooling oscillation:
  • there is about 1.5C PtV oscillation, about 100s period
  • The oscillation is not always present. See for instance from 01:30UT to 04:00UT
  • The temperature variation induces a correlated oscillation on the reading of capacitive sensor (possibly because of mechanical deformation)
