Grupe et al.,\nGCN Circ. 6509 ), was triggered at 02:38:41 UT (=T0) by the Suzaku Wide-band\nAll-sky Monitor (WAM) which covers an energy range of 50 keV - 5 MeV.\nThe observed light curve shows a single peaked structure with a duration (T90)\nof nearly 35 seconds. The fluence in 100-1000 keV was (8.2 +/- 2.4) * 10^-6 erg/cm^2.\nThe 1-s peak flux was 1.2 (+0.4, -0.3) photons/cm^2/s in the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from T0-4 to\nT0+36 sec is well fitted by a single power law model with a photon index\nof 2.5 +/ -0.3 (chi^2/d.o.f. = 31/21).\n\nAll the quoted errors are at statistical 90% confidence level, in which\nthe systematic uncertainties are not included.\n\nThe WAM light curve of this event is available at the following web cite.\n\nhttp://www.astro.isas.ac.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html",
