Weekly PEM meeting

2023/12/22(Fri) 17:00-
Regular meeting
Zoom2 : https://zoom.us/j/6676627462

General announcement

2023年も大変お世話になりました。
- PEM subsystemは今年もたくさんの結果を残すことができました。ありがとうございます。
- 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.
