We plan to start the O4 Observing run in mid-December 2022, though we are still working through delays resulting from the pandemic. An Engineering Run is planned to start in mid-November; low-latency alerts for candidate events identified during engineering time may be released, both to exercise the system and to preserve the scientific value. We are planning a webinar for late April to update the community about the status of work on the detectors and to discuss the remaining challenges in our current schedule.<\/p>\n\n\n\n<p>LIGO projects a sensitivity goal of 160-190 Mpc for binary neutron stars. Virgo projects a target sensitivity of 80-115 Mpc. KAGRA should be running with greater than 1 Mpc sensitivity at the beginning of O4, and will work to improve the sensitivity toward the end of O4.<\/p>\n\n\n\n<p>The most recent updates are always available at <a href=\"https:\/\/www.ligo.org\/scientists\/GWEMalerts.php\">https:\/\/www.ligo.org\/scientists\/GWEMalerts.php<\/a><\/p>\n\n\n\n<p>If you have any questions, please contact the Spokespersons:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Patrick Brady (Spokesperson, LIGO Scientific Collaboration)<br>&nbsp; &nbsp; lsc-spokesperson_AT_ligo\/org<\/li><li>Giovanni Losurdo (Spokesperson, Virgo Collaboration)<br>&nbsp; &nbsp; virgo-spokesperson_AT_ego-gw\/it<\/li><li>Jun\u2019ichi Yokoyama (Board Chair, KAGRA Scientific Congress)<br>&nbsp; &nbsp; kscboard-chair_AT_icrr\/u-tokyo\/ac\/jp<\/li><\/ul>\n\n\n\n<p>(Please replace \u201c_AT_\u201d into \u201c@\u201d and replace \u201c\/\u201d into \u201c.\u201d after it.)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[15 March 2022 update; next update by 15 May 2022] LIGO, Virgo, and KAGRA are closely coordinating to start th [&hellip;]<\/p>\n","protected":false},"author":8,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6,5],"tags":[],"class_list":["post-1632","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\/1632","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\/8"}],"replies":[{"embeddable":true,"href":"https:\/\/gwcenter.icrr.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/comments?post=1632"}],"version-history":[{"count":12,"href":"https:\/\/gwcenter.icrr.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/1632\/revisions"}],"predecessor-version":[{"id":1648,"href":"https:\/\/gwcenter.icrr.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/1632\/revisions\/1648"}],"wp:attachment":[{"href":"https:\/\/gwcenter.icrr.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/media?parent=1632"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gwcenter.icrr.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/categories?post=1632"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gwcenter.icrr.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/tags?post=1632"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
