Yamaoka, M. Ohno, Y. Hanabata, Y. Fukazawa, T. Takahashi, M. Tashiro,\nY. Terada, T. Murakami, and K. Makishima on behalf of the Suzaku WAM \nteam, report:\n\nThe long-duration, intense GRB 131118A (Collazzi, GCN 15503) has been\nobserved by Fermi (GBM: trigger 406508340), INTEGRAL (SPI-ACS), Swift \n(BAT), Suzaku (WAM), MESSENGER (GRNS), Mars Odyssey (HEND), and \nKonus-Wind, so far, at about 82737 s UT (22:58:57). The burst was \noutside the coded field of view of the BAT.\n\nWe have triangulated it to a 3 sigma error box whose\ncoordinates are:\n  ---------------------------------------------\n   RA(2000), deg                 Dec(2000), deg\n  ---------------------------------------------\n  Center:\n   349.863 (23h 19m 27s) -66.833 (-66d 49' 58\")\n  Corners:\n   350.415 (23h 21m 40s) -66.930 (-66d 55' 47\")\n   349.800 (23h 19m 12s) -66.926 (-66d 55' 32\")\n   349.313 (23h 17m 15s) -66.733 (-66d 44' 00\")\n   349.924 (23h 19m 42s) -66.740 (-66d 44' 23\")\n  ---------------------------------------------\nThe error box area is 162 sq. arcmin, and its maximum\ndimension is 29 arcmin (the minimum one is 12 arcmin). The Sun distance \nwas 81.6 deg.\n\nThe center of the GBM ground position (Collazzi, GCN 15503) is 2.6 deg \nfrom the center of the box.\n\nSome improvement in this triangulation is possible.",
