Hara (Univ. of Miyazaki), M. Ohno, M. Kokubun,\nM. Suzuki, T. Takahashi (ISAS/JAXA), S. Hong (Nihon U.), \non behalf of the Suzaku WAM team, report:\n\nThe Swift GRB 080413B (Swift/BAT trigger #309111 ; Stamatikos et al., GCN 7598) \nwas detected by the Suzaku Wide-band All-sky Monitor (WAM) which\ncovers an energy range of 50 keV - 5 MeV at 8:51:11.645 UT (=T0).\nThe observed light curve shows a single peak starting at T0-0s, \nwith a duration (T90) of about 2 seconds. The fluence in 150 - 1000 keV \nwas (1.4 +/- 0.3) x 10^-6 erg/cm^2. The 1-s peak flux measured from T0+1s was \n3.4 +/- 0.2 photons/cm^2/s in the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from T0-1s to T0+8s \nis fitted by a single power-law with a photon index of 3.02 (+0.36, -0.32) \n(chi^2/d.o.f = 16.7/16) in 150 - 1000 keV. All the quoted errors are at statistical \n90% confidence level, in which the systematic uncertainties are not included.\n\nThe light curves with 1-sec time resolution for this burst are now available at:\nhttp://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/untrig/grb_table.html",
