Hong (Nihon U.),\non behalf of the Suzaku WAM team, report:\n\nThe long GRB 090717A (Fermi-GBM trigger #269484574; Kara et al., GCN 9692),\ntriggered the Suzaku Wide-band All-sky Monitor (WAM) which covers an\nenergy range of 50 keV - 5 MeV at 00:49:32.019 UT.\n\nThe light curve shows a double pulse structure with a duration\n (T90) of 56 seconds. The fluence in 100 - 1000 keV was\n 1.10(-0.15, +0.12) x10^-5 erg/cm^2. The 1-s peak flux measured\nfrom T0+6 s was 3.14(-0.53, +0.36) photons/cm^2/s\nin the same energy range.\n\nPreliminary result shows that the time-averaged spectrum\nfrom T0 to T0+60 s is well fitted by a single power-law model with a\nphoton index of 2.13(-0.22, +0.33)  (chi^2/d.o.f. = 15.1/17).\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 now available at:\nhttp://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html",
