Makishima, on behalf of the Suzaku WAM\nteam, report:\n\nFermi (GBM), Konus-Wind, Swift (BAT), MESSENGER (GRNS), and Suzaku (WAM) \nobserved the long, hard GRB 110120A at about 15:59:39 UT (Fermi/GBM \ntrigger 317231981: Lin, GCN 11591). The burst was outside the coded \nfield of view of the BAT.\n\nWe have triangulated it to a 3 sigma error box whose coordinates are:\n-----------------------------------------------\n    RA(2000), deg              Dec(2000), deg\n-----------------------------------------------\nCenter:\n   60.481 (04h 01m 55s)   -10.548 (-10d 32' 51\")\nCorners:\n   56.433 (03h 45m 44s)    -5.247 (-05d 14' 48\")\n   62.714 (04h 10m 51s)   -13.354 (-13d 21' 16\")\n   64.578 (04h 18m 19s)   -14.953 (-14d 57' 11\")\n   58.278 (03h 53m 07s)    -7.456 (-07d 27' 21\")\n-----------------------------------------------\nThe error box area is 2.548 sq. deg.\nThis error box may be improved.\nBecause the Earth, the Wind, and the MESSENGER satellites are nearly \naligned at the moment (the angular distance between Wind and MESSENGER \nis only 5.7 deg), the annuli intersect at grazing incidence and the \nresulting 3-sigma box is long.\n\nA map is posted at http://www.ioffe.ru/LEA/GRBs/GRB110120_T57582/IPN/\nshowing the GBM best-fit position (blue star and circle), the IPN annuli \n(solid lines with centers dot-dashed), and the box (solid black closed \npolyline).",
