Makishima (Univ. of Tokyo), \non behalf of the Suzaku WAM team, report:\n\nThe bright long, Fermi-LAT GRB 100414A (Takahashi et al., GCN 10594; \nFermi/GBM trigger #292904423 / 100414097; Foley, GCN 10595) triggered the \nSuzaku Wide-band  All-sky Monitor (WAM) which covers an energy range \nof 50 keV - 5 MeV at 02:20:22.879 UT (=T0). \n\nThe observed light curve shows a multi-peaked structure starting at T0-1.5 s,\n ending at T0+24.5 s with a duration (T90) of about 22 seconds. \n The fluence in 100 - 1000 keV was 4.88(-0.36, +0.13)x10-5 erg/cm^2. \n The 1-s peak flux measured from T0+22.5 s was 6.13(-0.79, +0.40) \n  photons/cm^2/s in the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from \nT0-1.5 s to T0+24.5 s is well fitted by a GRB Band model as follows.\nthe low-energy photon index alpha: -0.56(-0.29, +0.37),\nthe high-energy photon index beta: -3.05(-0.53, +0.30),\nand the peak energy Epeak: 612(-53, +55) keV (chi^2/d.o.f = 34/23).\n\nDue to the brightness of this burst, a 3% systematic error was \n added for low energy channels.  In addition, there might be \n  some calibration uncertainties in these spectral parameters \n because GRB photons came to the WAM detector by passing through the \n  large Ne dewar of the X-ray micro-calorimeter (XRS). \nAll the errors are quoted at 90% confidence level.\n\nThe light curves for this burst are available at:\n http://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html",
