Golenetskii et. al.)\n\ntriggered the Suzaku Wide-band All-sky Monitor (WAM) which covers an\nenergy range\nof 50 keV - 5 MeV at 00:34:57.78 UT (=T0).\n\nThe observed light curve shows a single peak FRED T0-1 s,\nending at T0+69 s with a duration (T90) of about 54 seconds.\n\nThe fluence in 100 - 1000 keV was 3.71(-0.22, +0.11)x10-5 erg/cm^2.\n\nThe 1-s peak flux measured from T0+1.5 s was 7.31(-0.35, +0.35)\nphotons/cm^2/s in the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from\n\nT0-1 s to T0+69 s is well fitted by a GRB Band model as follows.\n\nthe low-energy photon index alpha: -0.43(-0.27, +0.31),\nthe high-energy photon index beta: -3.82(-1.33, +6.18),\nand the peak energy Epeak: 649.8(-44.5, +44.5) keV (chi^2/d.o.f = 31/27).\n\nAll the errors are quoted at 90% confidence level.\n\n\nThe light curves for this burst are available at:\nhttp://www.astro.isas.ac.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/1500.html",
