The fluence in 100 - 1000 keV was 1.36 (+/- 0.12) x10^-6 erg/cm^2.\nThe 1-s peak flux measured from T0+6 s was 2.17 (+0.35, -0.45)\nphotons/cm^2/s in the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from T0-10 s to\nT0+95 s is well fitted in 200 keV to 5 MeV by a single power-law with a\nphoton index of 2.64 (+0.34, -0.28) (chi^2/d.o.f = 12.5/14).\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 will be available at:\n\nhttp://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html",
