Zhang (IHEP), \nreport on behalf of the Insight-HXMT team: \n\nIn response to the LIGO-Virgo GW event S190421ar T0 = 2019-04-21 \n21:38:56 (UTC; GCN #24141), analysis of HXMT/HE data shows that the \nsatellite at T0 was in the South Atlantic Anomaly (SAA).\n\nAll measurements above are made with the CsI detectors operating in the \nregular mode with the energy range of about 80-800 keV (deposited energy). \nOnly gamma-rays with energy greater than about 200 keV can penetrate \nthe spacecraft and leave signals in the CsI detectors installed inside \nof the telescope. \n\nInsight-HXMT is the first Chinese space X-ray telescope, which was \nfunded jointly by the China National Space Administration (CNSA) and \nthe Chinese Academy of Sciences (CAS). \nMore information could be found at: http://www.hxmt.org.",
