General announcement
- KAGRA F2F meeting registration
- Thank you very much for many responses for the Commissioning support!
- Virgo ENV member have some plan to visit KAGRA about 1 month
- Jan., Feb. or Mar. one month
- Plan
- Noise hunting (PEM injection) toward the 10 Mpc would be first priority
- Power supply operation
- Magnetic injection
- Additional NN measurement
- Other
- O4a noise budget paper
- If you have a plan to write the paper using O4a data and PEM, please let me know.
- Start the investigation for the new subsystem, noise subtraction, under the SEO.
- First meeting in Japanese member, next week
