 * Zoom2 : https://zoom.us/j/6676627462

==== General announcement ====

 * 新年明けましておめでとうございます。
  * 2024年もよろしくお願いします。

 * Kamioka visiting plan
  * Yokozawa and Washimi-san have several budgets (共同利用)
    * So we want to call not only PEM members but also KAGRA members who are interested in onsite. 
    * If you want to visit Kamioka, please contact Yokozawa
  * Hoshino & Sato will stai Kamioka on February (3weeks?)

 * O4b
  * Break : mid-January - mid-March, 2024
  * Virgo : will join in March
  * KAGRA : Three-month observation around here

 * O4a noise budget paper
  * If you have a plan to write the paper using O4a data and PEM, please let me know.

==== Business travel (except for conferences) ====

 * To Kamioka
  * Hoshino (February?)
  * Sato (Febryary?)
 * From Kamioka
  * No plan

==== General issue ====

  * Effect of earthquake
   * Noto earthquake at 1/1
   * IMC : Need open in near future
    * Suspension health check, vacuum check, and so on
   * Other suspensions:
    * Type-C : IMMT1,2 OMMT1,2, OSTM health check ongoing
    * TYpe-Bp : Serious drift, check one by one, there are possibility to open the whole area
    * Type-B : No serious damage achieve LOCK_ACQUISITION, start health check soon
    * Type-A : Several drifting in MN oplev when we align with TM, but achive LOCK_AQCUISITION    

  * Cooling down
   * IX,EX,EY : Radiation shield cooling down : 84-88 K

   * EY : Started the cooling down duct shield
    * 98 K

   * Temperature change [[https://gwdet.icrr.u-tokyo.ac.jp/~controls/trendMon/finesse.html|url]]
   * After starting the cooling down after measuring the Q-value of sapphire fiber

  * Strategy for noise hunting
   * [[https://klog.icrr.u-tokyo.ac.jp/osl/?r=26848|klog26848]]

 * 出張PEM injection ([[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=14016|planning form]])
