Hi All:

The LIGO-Virgo-KAGRA collaborations have reviewed the readiness status of the detectors improvements and A+/AdV+ modifications in preparation for O4. As of November 2020, the O4 observing run is projected not to begin before June 2022, due to both key procurement delays and COVID-related delays. A number of significant modifications to detector systems during the next six months will refine the understanding of COVID impacts on the schedule. A revised projection of the O4 start date will be given in Spring 2021, based on lessons learned.

On February 25, 2020, KAGRA started observing run after its commissioning procedures and engineering runs.

KAGRA is a large-scale cryogenic gravitational-wave telescope developed in Kamioka, Hida City, Gifu Prefecture, Japan under the leadership of the University of Tokyo’s Institute for Cosmic Ray Research (ICRR) with contributions from the National Astronomical Observatory of Japan (NAOJ) and the High Energy Accelerator Research Organization (KEK). The construction started in 2010 and completed in the last year [press release].
