Hong (Nihon U.),\non behalf of the Suzaku WAM team, report:\n\nThe long GRB 080319C (Swift/BAT trigger #306778 ; Pagani et al.,\nGCN 7442) triggered the Suzaku Wide-band  All-sky Monitor (WAM)\nwhich covers an energy range of 50 keV - 5 MeV at 12:25:56 UT (=T0).\nThe observed light curve shows a multi-peaked structure starting at T0s,\nending at T0+14s with a duration (T90) of about 13 seconds.\nThe fluence in 100 - 1000 keV was 6.4(+0.4, -0.9)*10^-6 erg/cm^2.\nThe 1-s peak flux measured from T0+2s was 4.2(+0.2, -0.3) photons/cm^2/s\nin the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from\nT0s to T0+13s is well fitted by a power-law with exponential cutoff model:\n   dN/dE ~  E^{-alpha} * exp(-(2-alpha)*E/Epeak) with\n   alpha       0.67(+0.30, -0.36), and\n   Epeak       761(+255, -136) keV (chi^2/d.o.f. = 32.2/23).\n\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 \nhttp://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html",
