  * Maybe online style for Japanese member

 * Working style (COVID-19 related)
  * Some collaborator came to Kamioka. Please contact to Yokozawa if you plan to go to Kamioka.

 * KAKENHI proposal limit
  * NAOJ : Oct. 8
  * ICRR : Mostly end of Oct.(4th week deadline)
  * JSPS : Nov. 5 16:30 JST (final limit)

 * PEM DAQ racks
  * Use only IX and IY racks
  * Move the position of IX and IY racks

 * New PEMs toward O4
  * Many microphone
   * Not only tables but also booth
  * Position of magnetometer
  * Position of seismometer
  * Additional PEMs to PSL room
   * 120Hz noise
   * glitch study

   * Environmental part
      * Acoustic noise : Refer our PEM injection paper.
        * We can discuss whether we use [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=15103|the result of pre-O3 study]] for the noise budget paper.
      * Seismic noise : summarise the actual seismic nois during O3GK? (who?)
      * --(OMC leg vibration : 12th - 16th Sep. ?)--
      * AC power lines : Coherence analysis is done ([[http://klog.icrr.u-tokyo.ac.jp/osl/?r=14848]], Washimi)
      * Magnetic noise : skipped in this paper?
      * Newtonian : seismic newtonian -> from PTEP1 (or Francisca?) / water fluid newtonian -> skipped / air density -> skipped
   *We will held a noise budget meeting to summarize the current status, before the starting of heavy mine work. Details will be announced by KYamamoto-san(ToyamaU) soon later.
   * Next week, Washimi-san and Yokozawa will discuss with writing team. After that I will summarize again

  * Temperature control
   * Cooler ON, compressor ON, FFU ON, ...
   * IYC FFU glitch
   * Re-start the FFU on work after 7th Oct.

  * PEM Rack arrange
   * There are discussion about DAQ of the KAGRA PEM channels. PEM channels may be assigned in the IX0 and IY0 racks.
    * Less effect from other models(less data loss)
    * Change the place of the IX0 and IY0 rack (next to MCF and BS chamber?)
    * plan : [[https://docs.google.com/spreadsheets/d/1OHBOrNFt_Fpre-T-oSCkupGevc976d8T2PI9TVS_6pI/edit?usp=sharing|GoogleSpreadsheet]]
