Markwardt et al., GCN 6871, 6877)\nwas triggered by the Suzaku Wide-band  All-sky Monitor (WAM)\nwhich covers an energy range of 50 keV - 5 MeV at 2007-10-10 20:45:49 UT (=T0).\nThe observed light curve shows a single FRED-like peak,\nstarting at T0-3s, ending  at T0+10s, with a duration (T90) of about 5 seconds.\nThere is no signal corresponding to the pre-trigger pulse and the weak soft tail\ndetected by the Swift/BAT (GCN Report 92.1) and the Konus-Wind (GCN 6879)\nin the WAM energy band (50-5000 keV).\n\nThe fluence in 100 - 1000 keV was (1.8 +/- 0.3)*10^-6 erg/cm^2.\nThe 1-s peak flux measured from T0+1s was 1.1 +/- 0.3 photons/cm^2/s in the same\nenergy range.\n\nPreliminary result shows that the time-averaged spectrum from T0-3s to\nT0+10s is well fitted by a single power-law with a photon index\nof 3.2 (-0.5, +0.7) (chi^2/d.o.f = 6/8 ).\n\nAll the quoted errors are at statistical 90% confidence level,\nin which the systematic uncertainties are not included.\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",
