Bozzo and C. Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team,\nreport:\n\nThe very bright, long-duration GRB 220910A\n(AGILE detection: Ursi et al., GCN Circ. 32540;\nAstroSat-CZTI detection: Gopalakrishnan et al., GCN Circ. 32541)\nwas detected by AGILE (MCAL, AC), AstroSat (CZTI), Konus-Wind,\nFermi (GBM trigger 684481706), and INTEGRAL (SPI-ACS),\nat about 20910 s UT (05:48:30).\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     8.124 (00h 32m 30s)  -0.115 ( +0d 06' 55\")\n  Corners:\n     9.094 (00h 36m 23s)  -2.392 ( -2d 23' 30\")\n     7.404 (00h 29m 37s)  +2.183 ( +2d 11' 01\")\n     7.046 (00h 28m 11s)  +2.146 ( +2d 08' 44\")\n     8.743 (00h 34m 58s)  -2.426 ( -2d 25' 32\")\n  ---------------------------------------------\nThe error box area is 1.68 sq. deg, and its maximum\ndimension is 4.98 deg (the minimum one is 20.6 arcmin).\nThe Sun distance was 160 deg.\n\nThis box may be improved.\n\nThe IPN localization is consistent with, but reduces the area of,\nthe Fermi-GBM final localization (glg_healpix_all_bn220910242_v00).\n\nA triangulation map and HEALPix FITS file are posted at\nhttp://www.ioffe.ru/LEA/GRBs/GRB220910_T20910/IPN/\n\nThe Konus-Wind time history and spectrum will be given in a forthcoming\nGCN Circular.",
