==== Report of work (*:responsible person) ====

 * IFO: *Izumi, Miyamoto, Eleonora
  * Daily Beam check was confirmed at the REFL port yesterday evening.
  * Measurement of BS sensing and driving matrix and diagonalizarion of them.
   * This method should be automatically performed, but still we needs some work to be done.
  * T of ETMY was checked and improved. We need the same work for L.
  * LSC screen has been updated.

  * AOS: *Akutsu, Yokogawa
   * Green light reached to ETMY on Tuesday. Misalignment was ~100urad order.


 * IMC, CAL: Yokozawa, Yamamoto, Miyamoto
  * IMC Transmitted light is too low. Alignment should be checked.
  * Injection to MCE for calibration was tested.
  
 * VAC: Uchiyama
  * Vacuum level of X arm is degraded.


==== Work plan (*:responsible person) ====

 * Alignment: *Izumi
  * ETMY control, BS diagonalizatiom, Checking baffle PD of ETMX.
   * Needs power supply for QPD.

 * AOS: *Akutsu, Yokogawa
  * TMS alignment at ETMY.
  * Cooling will start at 10AM.
