Makishima (Univ. of Tokyo), on behalf of the Suzaku WAM team, report:\n\nThe long GRB 120602A (IPN; Hurley and Goldsten et al., GCN 13365, \nKonus-Wind; Golenetskii et al., GCN 13366)\ntriggered the Suzaku Wide-band  All-sky Monitor (WAM) which covers an \nenergy range of 50 keV - 5 MeV at 05:00:0.83 UT (=T0).\n\nThe observed light curve shows a multi-peaked structure starting at \nT0+5.8 s, ending at T0+59.8 s,  with a duration (T90) of about 54 \nseconds. The fluence in 100 - 1000 keV was\n1.97 (-0.03, +0.07) x 10^-4 erg/cm^2. The 1-s peak flux measured from\nT0+56.4s was 40.0 (+/-1.3) photons/cm^2/s in the same  energy range.\n\nPreliminary result shows that the time-averaged spectrum from T0s to\nT0+70s is well fitted by a power-law with exponential cutoff model:\n   dN/dE ~  E^{-alpha} * exp(-(2-alpha)*E/Epeak) with\n   alpha       1.49(-0.13, +0.12), and\n   Epeak       305 (-51, +40) keV (chi^2/d.o.f. = 67.7/48).\n\nAll the quoted errors are at statistical 90% confidence level,\nin which the systematic uncertainties are not included.\n\n----\nThe light curves with 1-second time resolution for this burst are \navailable at:\n\nhttp://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/untrig/grb_table.html",
