Cordier (CEA) on behalf of the SVOM-GRM team,\n\nand\n\nE. Burns on behalf of the IPN, report:\n\nA bright, short-duration, soft burst was detected by\nKonus-Wind and SVOM (GRM) at about 20396 s UT (05:39:56) on May 2.\n\nWe have triangulated it to a Konus-GRM annulus centered at\nRA(2000)=243.691 deg (16h 14m 46s)  Dec(2000)=-21.870 deg (-21d 52' 12\"),\nwhose radius is 39.329 +/- 0.068 deg (3 sigma).\n\nAmong known SGRs, only the position of SGR 1E1841-045 is inside the annulus.\nGiven the positional coincidence of this burst with\nSGR 1E1841-045, its time history, and softness of its spectrum\n(as observed by Konus-Wind), we conclude this burst likely originated from SGR 1E1841-045.\n\nA triangulation map is posted at\nhttp://www.ioffe.ru/LEA/SGRs/260502_T20396/IPN/\n\nThe time history and spectrum will be given in forthcoming GCN circulars.",
