Makishima (Univ. of Tokyo),\non behalf of the Suzaku WAM team, report:\n\nThe long, IPN localized GRB 121225B (K. Hurley et al., GCN 14103) was \ndetected by the the Suzaku Wide-band All-sky Monitor (WAM) which covers \nan energy range of 50 keV - 5 MeV at 10:01:03.165 UT (=T0).\n\nThe observed light curve shows double-peaked structure starting at \nT0-16s, ending at T0+70s with a duration (T90) of about 53 seconds. The \nfluence in 100 - 1000 keV was 4.80(+0.19/-0.25)x10^-5 erg/cm^2.\nThe 1-s peak flux measured from T0+9s was 8.50 photons/cm^2/s in the \nsame energy range.\n\nPreliminary result shows that the time-averaged spectrum from T0-16s to \nT0+70s is well fitted by a single power-law with a photon index of \n2.17(+0.07/-0.07) (chi^2/d.o.f = 32.8/30).\nAll the quoted errors are at statistical 90% confidence level,\nin which the systematic uncertainties are not included.\n\n----\nThe light curves with 1-sec time resolution for this burst are appeared at:\nhttp://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/untrig/grb_table.html",
