  * beam dumper from reflection beam of the PRM
  * Temperature monitor

 * ALS CARM/DARM
  * ALS CARM/DARM lock succeeded
  * Calibration confirmation
  * Transfer function measurement Type-A suspension
  * Noise budget

 * MICH 3f lock
  * Actuation efficiency measurement

 * Discussion of closing center area
  * Oplev pylon
  * Beam duct re-installation
  * New gate valve
  * Closing chambers around BS area

=== 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
