The\nfluence in 100 - 1000 keV was 1.48 (+1.67 / -0.99) x 10-6 erg/cm2.\nThe 1-s peak flux measured from T0+0 s was 1.4 (+0.4/-0.8)\nphotons/cm2/s in the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from T0+0 s to\nT0+0.5 s is well fitted by a single power-law with a photon index of\n2.17 (+0.53/-0.36) (chi2/d.o.f = 36.6/25).\n\nAll the quoted errors are at statistical 90% confidence level, in which\nthe systematic uncertainties are not included.\n\nThe light curves for this burst are available at:\n\nhttp://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html",
