Makishima (Univ. of Tokyo) on behalf of the Suzaku WAM team, report:\n\nThe long GRB 140308A (Konus-Wind detection: S. Golenetskii et al.,\nGCN 15943, IPN localization: S. Golenetskii et al., GCN 15941)\nwas triggered the Suzaku Wide-band All-sky Monitor (WAM)\nwhich covers an energy range of 50 keV - 5 MeV at 03:49:26.030 UT (=T0).\n\nThe observed light curve shows a multi-peaked structure starting at \nT0-10 s, ending at T0+80 s with a duration (T90) of about 64 seconds.\nThe fluence in 100 - 1000 keV was 4.02 (-0.78, +0.14) x10^-5 erg/cm^2.\nThe 1-s peak flux measured from T0+20 s was\n7.71 (-5.71, +0.07) photons/cm^2/s in the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from T0-10 s\nto T0+80 s is well fitted by a GRB Band model in 90 keV to 5 MeV.\nthe low-energy photon index alpha: -0.95 (-0.44, +1.11),\nthe high-energy photon index beta: -2.20 (-0.23, +0.14),\nand the peak energy Epeak: 386 (-128, +132) keV\n(chi^2/d.o.f = 24.9/25).\n\nDue to the brightness of this burst, a 3% systematic error was added for\nlow energy channels. All the quoted errors are at statistical 90% \nconfidence level.\n\nThe light curves for this burst will be available at:\nhttp://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html",
