Gardner on on behalf of the GRS-Odyssey GRB team,\nreport:\n\nThe short-duration GRB 240123C\nwas detected by Konus-Wind, INTEGRAL (SPI-ACS),\nSwift (BAT), and Mars-Odyssey (HEND)\nat about 83553 s UT (23:12:33). \nThe burst was outside the coded field of view of the BAT.\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  244.077 (16h 16m 19s) -58.857 (-58d 51' 25\")\n Corners:\n  240.883 (16h 03m 32s) -55.715 (-55d 42' 55\")\n  241.066 (16h 04m 16s) -56.037 (-56d 02' 14\")\n  248.066 (16h 32m 16s) -61.657 (-61d 39' 24\")\n  247.747 (16h 30m 59s) -61.386 (-61d 23' 11\")\n ---------------------------------------------\nThe error box area is 1219 sq. arcmin, and its maximum\ndimension is 7.0 deg (the minimum one is 3 arcmin).\nThe Sun distance was 58 deg.\n\nThis localization may be improved.\n\nA triangulation map and HEALPix FITS file are posted at\nhttp://www.ioffe.ru/LEA/GRBs/GRB240123_T83553/IPN\n\nThe Konus-Wind time history and spectrum will be given\nin a forthcoming GCN Circular.",
