Makishima (Univ. of Tokyo) on behalf of the Suzaku WAM team, report:\n\nThe long GRB 131029A (Fermi-LAT detection: A. von Kienlin, et al., GCN\n15401) triggered the Suzaku Wide-band All-sky Monitor (WAM) which covers \nan energy range of 50 keV - 5 MeV at UT 23:20:48.884 (=T0).\n\nThe observed light curve shows a two-peaked structure starting at\nT0-5.0 s, ending at T0+110 s with a duration (T90) of about 84 seconds.\nThe fluence in 100 - 1000 keV was 1.51 (-0.36, +0.24) *10^-5 erg/cm^2.\nThe 1-s peak flux measured from T0+4.0 s was\n1.55 (-0.92, +1.3) photons/cm^2/s in the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from\nT0-2 s to T0+110 s is well fitted by a single power-law with a photon\nindex of 1.87 (-0.17, +0.17) (chi2/d.o.f = 12.4/12).\n\nDue to the brightness of this burst, a 3% systematic error was added\nfor low energy channels.\nAll the quoted errors are at statistical 90% confidence 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",
