Hong (Nihon U.),\non behalf of the Suzaku WAM team, report:\n\nThe long GRB 070724B (Feroci et al., GCN 6668) triggered the Suzaku\nWide-band All-sky Monitor (WAM) which covers an energy range of 50 keV\n- 5 MeV at 23:25:09 UT (=T0).  The observed light curve with 1/64 sec\ntime resolution shows a multi-peaked structure with a duration (T90) of\nabout 41 sec.  The fluence in 100-1000 keV was 1.04 (+0.08,-0.07) X10^-5\nerg/cm^2. The 1-s peak flux measured from T0+39 sec to T0+40 sec was\n3.33 (+/- 0.40) photons/cm^2/s in the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from T0-2 sec to\nT0+43 sec is well fitted by a single power-law with a steep photon index\nof 2.8 +/- 0.2 (chi^2/d.o.f. = 17.3/21).\n\nAll the quoted errors are at statistical 90% confidence level,\nin which the systematic uncertainties are not included.\n\nThe light curves for this burst are available at:\nhttp://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html",
