Hong (Nihon U.),\non behalf of the Suzaku WAM team, report:\n\n\n\nThe IPN localized long GRB 080122 (Hurley et al., GCN 7211) \ntriggered the Suzaku Wide-band  All-sky Monitor (WAM) \nwhich covers an energy range of 50 keV - 5 MeV at 2008-01-22 18:32:45 UT (=T0).\n\nThe observed light curve shows a multi-peaked structure \nstarting at T0-2 s, ending at T+98 s,\nwith a duration (T90) of about 100 seconds.\nThe fluence in 100-1000 keV was 2.5 x 10^-5 erg/cm^2. \nThe 1-s peak flux measured from T0+5 s was 5.2 photons/cm^2/s in the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from\nT0-4 s to T0+119 s is well fit by a power-law with exponential cutoff model:\n  dN/dE ~  E^{-alpha} * exp(-(2-alpha)*E/Epeak)\n  alpha       1.28 (+0.43, -0.54), and\n  Epeak       420  (+326, -192) keV (chi2/dof = 15.8/24).\n\nAll the quoted errors are at statistical 90% confidence level,\nin which the systematic uncertainties are not included.\n\nThe light curve data for this burst is available at:\nhttp://www.astro.isas.ac.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html",
