Updates of Observing Run plan of KAGRA

LIGO-Virgo-KAGRA (LVK) collaboration is in the middle of Observation 4 (O4) run. Recently, LVK decided to extend the O4 run until October 7, 2025. At the same time, it was decided to have a break of O4 between April 1 and June 4, 2025.

KAGRA has been planning to rejoin O4 in the spring of 2025. Despite the changes to the O4 schedule, KAGRA will maintain our schedule of the preparation for rejoining O4. Additionally, KAGRA would like to make good use of this 2 month break to improve the readiness of the KAGRA detector and the data analysis. KAGRA plans to rejoin O4 from the first day after the break.
