Connaughton, M. Briggs, and C. Meegan, on behalf of the Fermi GBM team, A. von Kienlin, X. Zhang, A. Rau, V. Savchenko, E. Bozzo, and C. Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team, S. Barthelmy, J. Cummings, N. Gehrels, H. Krimm, and D. Palmer, on behalf of the Swift-BAT team, and K. Yamaoka, M. Ohno, Y. Hanabata, Y. Fukazawa, T. Takahashi, M. Tashiro, Y. Terada, T. Murakami, and K. Makishima on behalf of the Suzaku WAM team, report: The long-duration, intense GRB 120707A (Younes, GCN 13422) has been observed by Fermi (GBM: trigger 363381140), Konus-Wind, INTEGRAL (SPI-ACS), Swift (BAT), Mars Odyssey (HEND), and Suzaku (WAM), so far, at about 69140 s UT (19:12:20). The burst was outside the coded field of view of the BAT. We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 291.874 (19h 27m 30s) -32.770 (-32d 46' 12") Corners: 293.104 (19h 32m 25s) -36.566 (-36d 33' 56") 292.808 (19h 31m 14s) -37.093 (-37d 05' 36") 290.585 (19h 22m 20s) -27.663 (-27d 39' 48") 290.769 (19h 23m 05s) -26.473 (-26d 28' 23") --------------------------------------------- The error box area is 3.50 sq. deg, and its maximum dimension is 10.8 deg. This box can be improved. A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB120707_T69146/IPN/
