 * Type A:
  * ETMX yaw position was adjusted and upper tower ETMX seems to be fine. Oplev is off from the center and it means that cryo payload may be touching something. Tomaru-kun will check it today.
  * ETMX TF function measurement showed that LVDT gain was too low.
  * ETMY: f3 was stuck.
  * ITMX: It was turned out that BF was not cooled down.
 * Type B:
  * BS was recovered and chamber was closed. Health check showed that mechanically everything was OK.
  * Alignment of BS to REFL using ITMY was done.
  * SR2 seems to be OK, but oplev shows something wrong. Will open chamber.
  * SR3 is OK.
 * Type Bp:
  * PRM needs more work.
 * Type B: SR2: We found ghost beam of oplev for SR2, and we need several works to fix it and others.
 * Type Bp: PRM: We found nothing was touching except for cable, and we found loosen screws. We will fix them today.
 * Type A: ETMX will be fixed for
 * MIF: Green laser was swapped. We noticed that the AC power was low, and that is the cause of mulfunction.
  * Beat note is somehow low.
  * OMC rack is being implemented specially for circuits.
  * Green light injection for SR2 table by changing laser source will be done today. Aluminum foil will be put at SR2 table.

 * CRY: Temperature of BF of ITMX was fixed and shows correct one. ITMY was connected but still show some fake one.
  * Touching around Cryopayload will be checked today.
