  * Interferometer status
   * Several morning runs were held. They are silent run after the IFO commissioning.
    * We can use the PEM injection and calibration line study in future
    * See the detail in [[http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/DET/RUN/MORNINGRUN2019|url]]
    * Silent run -> Some excitation(including calibration line) -> PEM injection -> Hardware injection

  * Weekly PEM injection
   * Commissioning team suggest to have a weekly PME injection/measurement day with interferometer signal
   * First candidate : Every Friday
   * Show the plan for the PEM injection 

  * Chrome Book project (Portable PEM researcher)
   * http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/PEM/Portable
   * We prepared two PEM Chromebook  
   * There are many project to collaborate with the instruments
    * IOO, vibration, sound and magnetometer measurements inside the PSL room [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=10173|klog10173]], [[attachment:peak.txt|list]]
    * ALS, the green fiber noise
