Times and sky\nlocalizations are fictitious. ***\n\nWe identified the compact binary merger candidate\nMS200619bf during real-time processing of data from LIGO\nHanford Observatory (H1) and LIGO Livingston Observatory\n(L1) at 2020-06-19 10:25:22.98 UTC (GPS time:\n1276597540.98). The candidate was found by the SPIIR\n[1] analysis pipeline in the early warning configuration. An Early Warning GCN Notice was issued 28 seconds before the projected merger time. The GCN\nNotice included the standard data products associated\nwith CBC alerts, namely localization [2] and source\nclassification [3].\n\nHowever, this Early Warning alert (MS200619bf) is no\nlonger of interest because it was not detected by the\nregular, full-bandwidth search.\n\n[1] Qi Chu, PhD Thesis, The University of Western Australia (2017)\n[2] Singer & Price PRD 93, 024013 (2016)\n[3] Chatterjee et al.
