• Regular meeting meeting

• Web meeting with Zoom2 (Zoom2)

Agenda

• General issue
  • FPMI was locked!
    • We can obtain the engineering run like data at 23rd August 12:00-19:00 (lower noise from ~18:00-)
  • Early morning interferometer
    • We started the early morning interferometer between the activity between IFO commissioning and suspension commissioning

    • Silent run -> Some excitation(including calibration line) -> PEM injection -> Hardware injection

  • KAGRA F2F meeting 8/22-24
