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.<\/p>\n<p>Sincerely,<br \/>\nPatrick, Giovanni, Hisaaki, Dave, Albert, Stavros, Takaaki, Masatake<\/p>\n","protected":false},"excerpt":{"rendered":"<p>December 9, 2020 Hi All: The LIGO-Virgo-KAGRA collaborations have reviewed the readiness status of the detecto [&hellip;]<\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6,5],"tags":[],"class_list":["post-1489","post","type-post","status-publish","format-standard","hentry","category-news","category-latestnews"],"_links":{"self":[{"href":"https:\/\/gwcenter.icrr.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/1489","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gwcenter.icrr.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gwcenter.icrr.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gwcenter.icrr.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/gwcenter.icrr.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/comments?post=1489"}],"version-history":[{"count":2,"href":"https:\/\/gwcenter.icrr.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/1489\/revisions"}],"predecessor-version":[{"id":1491,"href":"https:\/\/gwcenter.icrr.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/1489\/revisions\/1491"}],"wp:attachment":[{"href":"https:\/\/gwcenter.icrr.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/media?parent=1489"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gwcenter.icrr.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/categories?post=1489"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gwcenter.icrr.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/tags?post=1489"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
