Hong (Nihon U.), \non behalf of the Suzaku WAM team, report:\n\nThe long 080727C (Swift/BAT trigger #318170; Parsons et al., GCN 8035)\ntriggered the Suzaku Wide-band All-sky Monitor (WAM) which\ncovers an energy range of 50 keV - 5 MeV at 23:07:51.558 UT (=T0).\nThe observed light curve shows two peaks, starting at T0-13s, ending\nat T0+70s, with a duration (T90) of about 54 seconds. The fluence in 150 - 1000 keV \nwas (6.0 +/- 0.7) x 10^-6 erg/cm^2. The 1-s peak flux measured from T0+9s was \n0.78 +/- 0.12 photons/cm^2/s in the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from T0-7s to T0+47s \nis fitted by a single power-law with a photon index of 1.83 +/- 0.18\nin the 150 - 1000 keV range (chi^2/d.o.f = 6.1/11). All the quoted errors are at statistical \n90% confidence level, in which the systematic uncertainties are not included.\n\nThe light curves with 1/64 sec time resolution for this burst are now available at:\nhttp://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html",
