Gardner on on behalf of the GRS-Odyssey GRB team,\nreport:\n\nThe long-duration GRB 241021A was detected by\nKonus-Wind, INTEGRAL (SPI-ACS), and Mars-Odyssey (HEND)\nat about 53930 s UT (14:58:50).\n\nWe have triangulated it to a preliminary, 3 sigma error box\nwhose coordinates are:\n---------------------------------------------\n  RA(2000), deg                 Dec(2000), deg\n ---------------------------------------------\n Center:\n  267.026 (17h 48m 06s) +29.592 (+29d 35' 31\")\n Corners:\n  265.186 (17h 40m 45s) +28.733 (+28d 43' 57\")\n  268.672 (17h 54m 41s) +30.598 (+30d 35' 53\")\n  268.925 (17h 55m 42s) +30.399 (+30d 23' 57\")\n  265.442 (17h 41m 46s) +28.544 (+28d 32' 37\")\n ---------------------------------------------\nThe error box area is 3597 sq. arcmin, and its maximum\ndimension is 3.6 deg (the minimum one is 16 arcmin).\nThe Sun distance was 69 deg.\n\nThis localization may be improved.\n\nA triangulation map and a HEALPix FITS file are posted at\nhttp://www.ioffe.ru/LEA/GRBs/GRB241021_T53930/IPN\nThe HEALPix triangulation map is the multi-order HEALPix in units of\nprobability density.\n\nThe Konus-Wind time history and spectrum will be given\nin a forthcoming GCN Circular.\n",
