Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team,\nreport:\n\nA bright, short-duration, soft burst has been observed by\nKonus-Wind, INTEGRAL (SPI-ACS), and Swift (BAT), so far,\nat about 536 s UT (00:08:56) on August 5.\nThe burst was outside the coded field of view of the BAT.\n\nWe have triangulated it to a Konus-BAT annulus centered at\nRA(2000)=313.877 deg (20h 55m 31s) Dec(2000)=-20.391 deg (-20d 23' 28\"),\nwhose radius is 46.762 +/- 0.249 deg (3 sigma) and\nto a Konus-SPI-ACS annulus centered at\nRA(2000)=310.504 deg (20h 42m 01s) Dec(2000)=-16.410 deg (-16d 24' 34\"),\nwhose radius is 41.919 +/- 0.512 deg (3 sigma).\n\nThis localization may be improved.\n\nThe position of SGR 1935+2154 is inside the annuli\nat 7.2 arcmin from the center line of the Konus-BAT annulus.\n\nGiven the positional coincidence of this burst with SGR 1935+2154, its \ntime history, and softness of its spectrum  (as observed by Konus-Wind), \nwe conclude this burst is likely originated from SGR 1935+2154.\n\n\nA triangulation map is posted at\nhttp://www.ioffe.ru/LEA/SGRs/210805_T00539/IPN/\n\nThe time history and spectrum will be given in forthcoming GCN Circulars.",
