Makishima (Univ. of Tokyo), on behalf of the Suzaku WAM team, report:\n\nThe long GRB 110715A (Swift/BAT trigger #457330 ; Sonbas et al., GCN 12158) \ntriggered the Suzaku Wide-band  All-sky Monitor (WAM)\nwhich covers an energy range of 50 keV - 5 MeV at 13:13:49.914 UT (=T0).\n\nThe observed light curve shows a multi-peaked structure starting at T0,\nending at T0+4s, followed by a weaker emission seen up to T0+20s \nwith a duration (T90) of 8 seconds.\nThe fluence in 100 - 1000 keV was 1.28 (-0.06, +0.07) x10^-5 erg/cm^2.\nThe 1-s peak flux measured from T0+3s was 20.3 (-1.1, +1.0) photons/cm^2/s \nin the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from T0-3s to\nT0+20s is well fitted by a single power-law with a photon index\nof 2.67 (-0.18, +0.19) (chi^2/d.o.f = 24.0/15).\nAll the quoted errors are at statistical 90% confidence level.\n\nThe light curves for this burst will be available at:\nhttp://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html",
