Chuang (NCU), K. Nakazawa, K. Makishima (Univ.\nof Tokyo),\non behalf of the Suzaku WAM team, report:\n\nThe bright short GRB 110529A  (McEnery et al., GCN 112044)\ntriggered the Suzaku Wide-band  All-sky Monitor (WAM) which covers an\nenergy range of 50 keV - 5 MeV at 2011-05-29 00:48:42.855 UT (=T0).\n\nThe observed light curve shows a single FRED-like peak\nstarting at T0s, ending  at T0+0.438s, with a duration\n(T90) of 0.344 +/- 0.049 seconds.\nThe fluence in 100 - 1000 keV was 1.93 (+/- 0.12) x 10^-6 erg/cm^2.\n The 1-s peak flux measured from T0s was 7.16 (+/- 0.45) photons/cm^2/s\nin the same  energy range.\n\nPreliminary result shows that the time-averaged spectrum from\nT0s to T0+0.5s is well fitted by a power-law with exponential cutoff model:\n  dN/dE ~  E^{-alpha} * exp(-(2-alpha)*E/Epeak) with\n  alpha       1.02 (-0.20, 0.16)), and\n  Epeak       1052 (-196, +254) keV (chi^2/d.o.f. = 55.9/52).\n\nWe also shows the results with the same spectrum\nfitted by a GRB Band model fixing beta of -2.5\nthe low-energy photon index alpha: -0.80 (-0.26, 0.34),\nthe high-energy photon index beta: -2.5 (fixed),\nand the peak energy Epeak: 791 (-161, 242) keV (chi^2/d.o.f = 53.6/52).\n\nAll the quoted errors are at statistical 90% confidence level.\n\nThe light curves for this burst are available at:\n http://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html",
