Makishima (Univ. of Tokyo),\n\nThe short hard intense GRB111222A (localized by IPN: Hurley et al., GCN 12714)\nwas detected by the Suzaku Wide-band All-sky Monitor (WAM) which covers \nan energy range of 50 keV - 5 MeV at 14:51:55 UT (=T0).\n\nThe observed light curve shows a double-peaked structure starting at\nT0 s, ending at T0+2 s with a duration (T90) of about 1 seconds. \nThe fluence in 100 - 1000 keV was 3.98 (-1.21, +0.74) x 10^-6 erg/cm^2. \nThe 1-s peak flux measured from T0 s was 4.70 (-1.18, +1.00) \nphotons/cm^2/s in the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from T0 to\nT0+2 s is well fitted by a power-law with exponential cutoff model:\n dN/dE ~  E^{-alpha} * exp(-(2-alpha)*E/Epeak) with\n alpha : -0.28 (-0.49, +0.43), and\n Epeak : 629 (-50, +61) keV (chi^2/d.o.f. = 94.8/98).\nAll the quoted errors are at statistical 90% confidence level.\n\nThe light curves for this burst are available at:\nhttp://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/untrig/grb_table.html",
