  * Y/YY Acceptance check IMC~PRM
  * X/XX Closing IMM-PRM and SRM-OMC

=== Progress of commissioning ===

 * X arm commissioning
  * End X IM 81K
  * Investigation of the noise in the new oplev light source
  * Investigation of the ADC noise

 * Y arm commissioning
  * Pumping down ongoing
  * IY duct shield cooling (8/5- Started)

 * Beam dump around IFI
  * Many ghost beam
  * beam dumper from reflection beam of the PRM
  * Temperature monitor

 * ALS CARM/DARM
  * ALS CARM/DARM lock succeeded
  * Transfer function measurement Type-A suspension
  * Now the noise level is limited by the ALS after fiber noise cancellation

 * Find IR resonance improved
  * After recovery of the alignment to AS table, FPMI trial will start

 * MICH 3f lock
  * Actuation efficiency measurement
 
 * TCam analysis
  * Find the beam position [[https://klog.icrr.u-tokyo.ac.jp/osl/?r=21839|klog#21839]]

=== Interesting data ===

 * X arm cavity
  * Both IR and GR
  * Glitch investigation of the ITMX ADC
  * Glitch investigation of the MN oplev light source

 * Y arm commissioning
  * Both IR and GR

 * Center area commissioning
  * MICH 3f lock
   * Check the lock information

  * ALS CARM/DARM
   * Check the lock information

  * IMC (Input Mode Cleaner)
   * ASC (Alignment Sensing and Control) done
   * Long term stability check
    * Beam power, beam position, oplev monitoring
   * Glitch investigation
   * Temperature dependence
   * Relationship between PSL room
   * With PEM channels
   * (Hammering test?)

  * OMC
   * Invesigation will continue after closing the center area
   * Because the BS is too fluctuate, it became difficult to investigate		   * 9/13 - 9/16 Investigation of the ghost beam IFI and acceptance check
