Baumgartner,\net al. , GCN 14708) triggered the Suzaku Wide-band All-sky Monitor (WAM)\nwhich covers an energy range of 50 keV - 5 MeV at UT 14:21:27.030(=T0).\n\nThe observed light curve shows a multi-peaked structure starting at\nT0-0.5 s, ending at T0+13 s with a duration (T90) of about 7.4 seconds.\nThe fluence in 100 - 1000 keV was 5.26 (-0.36, +0.39) *10^-5 erg/cm^2.\nThe 1-s peak flux measured from T0+4.5 s was\n20.26 (-0.92, +1.12) photons/cm^2/s in the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from\nT0-1 s to T0+13 s is well fitted by a GRB Band model as follows.\nthe low-energy photon index alpha: -0.87 (-0.13, +0.10),\nthe high-energy photon index beta: -2.68 (-0.36, +0.14),\nand the peak energy Epeak: 1426 (-123, +221) keV,\n(chi^2/d.o.f = 36.3/28).\n\nDue to the brightness of this burst, a 3% systematic error was added\nfor low energy channels.\nAll the quoted errors are at statistical 90% confidence level.\n\nThe light curves for this burst are available at:\nhttp://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html",
