Urata, P. Tsai, C-J. Chuang (NCU), K. Nakazawa, \nK. Makishima (Univ. of Tokyo), on behalf of the Suzaku WAM team, report:\n\nThe bright, long GRB110825A (localized by IPN; Hurley et al. GCN 12307) \ntriggered the Suzaku Wide-band All-sky Monitor (WAM) which covers an \nenergy range of 50 keV - 5 MeV at 02:27:03.410 UT (=T0).\n\nThe observed light curve shows multiple peaks starting at T0-3 s, ending\nat T0+8 s, with a duration (T90) of about 6.9 seconds. The fluence in\n the 100 - 1000 keV range was 1.88 +/- 0.14 x 10^-5 erg/cm^2. \nThe 1-s peak flux measured from T0+3 s was 17.0 +/- 0.8 photons/cm^2/s\nin the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from T0-3 s to\nT0+8 s is well fitted by a power-law with exponential cutoff model:\n dN/dE ~  E^{-alpha} * exp(-(2-alpha)*E/Epeak) with\n alpha :     1.28 (-0.40, +0.34), and\n Epeak :     248 (-47, +41) keV (chi^2/d.o.f. = 19.4/21).\n\nAll the quoted errors are at statistical 90% confidence level,\nin which systematic uncertainties are not included.\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",
