GCN 15371) was detected by the the\nSuzaku Wide-band All-sky Monitor (WAM) which covers an energy range of\n50 keV - 5 MeV at 21:35:31 UT (=T0).\n\nThe observed light curve shows a single peak with a duration (T90) of\nabout 45 seconds.\nThe fluence in 100 - 1000 keV was 4.26 (+0.84/-2.27) x 10^-6 erg/cm^2.\nThe 1-s peak flux measured from T0+2 s was\n0.73 (+0.26/-0.55) photons/cm^2/s in the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from T0-5 s to\nT0+5 s is well fitted by a single power-law with a photon index of\n2.13 (+0.28/-0.36) (chi^2/d.o.f = 12.4/14).\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/untrig/grb_table.html",
