Makishima (Univ. of Tokyo), S. Hong\n(Nihon U.), on behalf of the Suzaku WAM team, report:\n\nThe long GRB 100119A (Swift BAT trigger #383063; Mangano et al. GCN 10348)\ntriggered the Suzaku Wide-band All-sky Monitor (WAM) which covers an\nenergy range of 50 keV - 5 MeV at 18:25:09.630 UT (=T0).\n\nThe observed light curve shows a complicated structure, with\noverlapping pulses. The duration (T90) was about 24 seconds.\nThe fluence in 100 - 1000 keV band is 4.55(-0.21, +0.17) x 10^-6 erg/cm2\nwith a 1-s peak flux measured from T0+18.5 sec of 6.94 (-0.63, +0.32)\nphotons/cm^2/s in the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from\nT0-3.5 s to T0+37.5 s is well fitted by a cut off power-law model:\n dN/dE ~  E^{-alpha} * exp(-(2-alpha)*E/Epeak) with\n alpha      1.17 (-0.27, +0.26), and\n Epeak      510 (-45, +54) keV (chi^2/d.o.f. = 26.7/24).\n\nDue to the brightness of this burst, a 3% systematic error\nwas added for low energy channels.\nAll the quoted errors are at 90% confidence level.\n\nThe light curves of this event are available at the following URL:\n http://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html\n\n=========================================================================",
