Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team,\nreport:\n\nThe very bright, long-duration GRB 190305A was detected by\nAGILE (MCAL; Ursi et al., GCN Circ. 23930),\nMAXI (GSC; Nakahira et al., GCN Circ. 23933),\nCALET (GBM trigger 1235826131), Konus-Wind, INTEGRAL (SPI-ACS),\nSwift (BAT), and Insight (HXMT/HE; Xiao et al., GCN Circ. 23934)\nat about 47118 s UT (13:05:18).\nThe burst was outside the coded field of view of the BAT.\n\nWe have triangulated this GRB to a Konus-INTEGRAL annulus centered at\nRA(2000)=340.399 deg (22h 41m 36s) Dec(2000)=-10.588 deg (-10d 35' 17\"), \nwhose radius is 47.461 +/- 0.110 deg (3 sigma), and\nto a Konus-BAT annulus centered at\nRA(2000)=337.304 deg (22h 29m 13s) Dec(2000)=-7.381 deg (-7d 22' 51\"), \nwhose radius is 51.552 +/- 0.132 deg (3 sigma).\n\nThe position of the XRT source #1 (D'Ai et al., GCN Circ. 23935)\nlies 0.019 deg from the center line of the Konus-BAT annulus\nand 0.136 deg from the center line of the Konus-INTEGRAL annulus,\nsupporting the conclusion that this source is the GRB counterpart.\n\nThis localization may be improved.\n\nA triangulation map is posted at\nhttp://www.ioffe.ru/LEA/GRBs/GRB190305_T47118/IPN/\n\nThe Konus-Wind time history and spectrum will be given in a forthcoming \nGCN Circular.",
