 * Remote participants by eZuce: Takahashi, Aso

 * Report of work (*:responsible person)
  * Vibration Isolation,
   * Restarted the BS realtime model.

  * Alignment: Izumi, Okutomi
   * ETMY transfer function has a different shape from what was measured before in the air. It means that ETMY might be touching somewhere.
    * For vertical, below BF transfer function seems to be OK.
    * Yaw might be rotating too much.
     * After 1/17, ETMY started showing something strange. Stiffness changed gradually, but Q did not change much.


 * Work plan (*:responsible person)

  * Alignment: *Izumi, Okutomi
    * We will rotate IP yaw to release somewhere touching. This work takes 1day at least.
    * Detchar for spectrum of suspension is necessary as soon as possible.

  * Vacuum
    * Gate valve will be closed today.
    * Needs 2days for evacuation. If once evacuated, cooling will be late ~2weeks.
 
  * Type B
   * SR assembly continues.

 * Laser hazard: PSL. At some in this evening, it will be the are over the SR line for double-checking the IMC alignment. Kokeyama is responsible for it.

 * Weekly
  * Week of 2/5
   * Finding causes of ETMY trouble.
    * Evacuation might be needed if ETMY is touching somewhere.
    * Cooling also will be delayed for 2weeks or so.

 * Issues
  * The ETMY mirror showed a strange scattering pattern.
