26 Mar 2020 — Due to the COVID-19 pandemic, LIGO observing mode operations will end on March 27, 2020. The decision to halt O3 was not an easy one, however the current worldwide COVID-19 pandemic demands that we make public health and safety our top priority. It is unknown at this time when observing mode operations may resume. In spite of the early suspension, the O3 run has been a tremendous success and we look forward to the science to come from the O3 events and future observing runs with the gravitational-wave detector network.For more additional details, see
