Hong (Nihon U.), on behalf of the Suzaku WAM team, report:\n\nThe short/hard GRB081024B (Fermi-LAT detected ; Omodei GCN8407,\nFermi-GBM triggered ; Connaughton and Briggs, GCN 8408) triggered the\nSuzaku Wide-band All-sky Monitor (WAM) which covers an energy range\nof 50 keV - 5 MeV at 21:22:40.526 UT (=T0). \n\nThe observed light curve shows double-peaked structure with a duration\n(T90) of about 0.4 second. \nThe fluence in 100 - 1000 keV was 2.7(+0.7, -1.0) X 10^-7 erg/cm^2. \nThe peak flux within 0.5 second was 1.1(+0.3, -0.5) photons/cm^2/s in\nthe same energy range.\n\nPreliminary result shows that even at least 2 MeV photons have been\ndetected, and the time-averaged spectrum from T0 to T0+0.5s is well\nfitted by a single power-law with a photon index of 1.24(+0.25, -0.19)\n(chi^2/d.o.f = 12.3/14). All the quoted errors are at statistical 90%\nconfidence level, in which the systematic uncertainties are not included. \n\nThe light curves for this burst are availabel at:\nhttp://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html",
