Its\nfalse alarm rate, as determined by the online analysis, is 1.26e-07 Hz\nor about 4 per year. The event's properties can be found at this URL:\n\nhttps://gracedb.ligo.org/events/G284239\n\nNo other GW event candidates were identified within a 300 s window\nbefore or after G284239.\n\nA sky map, LIB_skymap.fits.gz, is available to be retrieved from the\nGraceDB event page.  This is the preferred sky map at this time.\nThe 50% confidence region covers 1029 squares degrees and the 90%\nconfidence region covers 3593 square degrees.\n\nThe GCN Notice and Circular were delayed by more than 16 hours\ndue to a technical problem, now resolved.\n\nUpdates on our analysis of this event will be sent as they become\navailable.",
