Hong (Nihon U.), \non behalf of the Suzaku WAM team, report:\n\nThe long GRB 081203B (Swift/BAT Slew Survey, Copete et al., GCN Circ. 8600, \n8602) triggered the Suzaku Wide-band  All-sky Monitor (WAM) which covers \nan energy range of 50 keV - 5 MeV at 2008-12-03 13:51:31.94713598 UT (=T0). \nThe observed light curve shows a multi-peaked structure starting at T0-0.5s, \nending at T0+64s with a duration (T90) of about 45 seconds. The fluence in\n100 - 1000 keV was 2.9 x 10^-5 erg/cm^2. The 1-s peak flux measured from \nT0+11.25s was 2.9 photons/cm^2/s in the same energy range.\nPreliminary result shows that the time-averaged spectrum from\nT0-3s to T0+64s is well fitted by a power-law with exponential cutoff model:\n  dN/dE ~  E^{-alpha} * exp(-(2-alpha)*E/Epeak) with\n  alpha       1.2 -0.2 +0.3 and\n  Epeak       304 -20 +22 keV (chi^2/d.o.f. = 50.6/28).\nAll the quoted errors are at statistical 90% confidence level,\nin which the systematic uncertainties are not included.\nThe light curves for this burst are available at:\n\n http://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html",
