Terada,\nT.Murakami, and K.Makishima on behalf of the Suzaku WAM team\n\nreport:\n\nKonus-Wind, INTEGRAL-SPI-ACS, RHESSI, Suzaku-WAM, and Swift-BAT observed \na bright short hard GRB at about 22:42:47 UT on March 3.\nThe burst was outside of the field of view of Swift-BAT, so it was not\nimaged. Ulysses was off, and Odyssey did not observe this event.\n\nWe have derived a triangulation annulus centered at\nRA(2000), Dec(2000) = 42.325 deg,  +16.869 deg,\nwhose radius is 73.266 �0.173 deg (3 sigma).\nCombining the all available data we have triangulated the GRB to\nthe section of this annulus between\nRA(2000), Dec(2000)= 221, +26 and 230, +71 degrees.\n\nAs observed by Konus-Wind it had a duration of ~0.6 s,\nfluence 1.16(-0.20,+0.19)x10^-5 erg/cm2,\nand the 16-ms peak flux measured from T0+0.206 s\n4.27(-1.11,+1.08)x10^-5  erg/cm2/s\n(both in the 20 keV - 5 MeV energy range).\n\nThe spectrum integrated over the most intense part of the burst\n(accumulated from T0 to T0+0.256 s)\nis well fitted in the 20 keV - 5 MeV range\nby GRBM (Band) model for which:\nthe low-energy photon index is alpha = -0.35(-0.16, +0.18),\nthe high energy photon index beta = -2.51(-2.32, +0.48),\nthe break E0 = 702(-232, +256) keV (chi2 = 52/41 dof).\nThe peak energy Epeak = 1158(-281, +305) keV.\n\nAll the quoted errors are at the 90% confidence level.",
