Starr,\non behalf of the GRS-Odyssey GRB team, report:\n\nThe long-duration GRB 190805B\n(MAXI/GSC detection: Sato et al., GCN Circ. 25271;\nFermi/GBM detection: Hamburg & Meegan, GCN Circ. 25277)\nwas detected by Fermi (GBM trigger 586673165), INTEGRAL (SPI-ACS),\nMars-Odyssey (HEND), Konus-Wind and MAXI (GSC) at about 17159 s UT\n(04:45:59).\n\nWe have triangulated it to a Konus-HEND annulus centered at\nRA(2000)=321.552 deg (21h 26m 13s)  Dec(2000)=-16.302 deg (-16d 18' \n08\"),\nwhose radius is 61.012 +/- 0.062 deg (3 sigma).\n\nOnly a rectangular error box of the MAXI/GSC position reported\nby Sato et al. (GCN Circ. 25271) is consistent with the annulus.\nThe annulus combined with the MAXI (90 % containment, statistical-only)\nlocalization gives the following error box:\n---------------------------------------------\n    RA(2000), deg                 Dec(2000), deg\n   ---------------------------------------------\n   Center:\n    212.376 (14h 09m 30s) +19.776 (+19d 46' 32\")\n   Corners:\n    212.356 (14h 09m 25s) +20.078 (+20d 04' 39\")\n    212.487 (14h 09m 57s) +20.071 (+20d 04' 15\")\n    212.395 (14h 09m 35s) +19.474 (+19d 28' 25\")\n    212.265 (14h 09m 03s) +19.480 (+19d 28' 49\")\n   ---------------------------------------------\nThe error box area is 267 sq. arcmin (a factor of 16\nsmaller than that of the MAXI error box), and its maximum\ndimension is 38 arcmin (the minimum one is 7 arcmin).\nThe Sun distance was ~73 deg.\n\nThe box is partially covered with the Swift XRT observations\nreported by Perri et al. (GCN Circ. 25279).\n\nThis box may be improved.\n\nA triangulation map is posted at\nhttp://www.ioffe.ru/LEA/GRBs/GRB190805_T17159/IPN/",
