Hong (Nihon U.), on behalf of the Suzaku WAM team, report:\n\nThe long GRB 081025 (Copete et al., GCN 8409)\ntriggered the Suzaku Wide-band  All-sky Monitor (WAM)\nwhich covers an energy range of 50 keV - 5 MeV at 2008-10-25 08:23:07 UT (=T0).\nThe observed light curve shows a multi-peaked structure\nstarting at T0-0.5s, ending at T0+21.5s,\nwith a duration (T90) of about 22 seconds.\nThe fluence in 100 - 1000 keV was 3.8(-0.7, +0.5)*10^-06 erg/cm^2.\nThe 1-s peak flux measured from T0 was 1.5 +/- 0.2 photons/cm^2/s\nin the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from T0-0.5s to\nT0+21.5s is well fitted by a single power-law with a photon index\nof 1.93 (-0.25, +0.29) (chi^2/d.o.f = 10/9).\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",
