Hong (Nihon U.), on behalf of the Suzaku WAM team, report:\n\nThe long GRB 080623 (Swift/BAT trigger #315080 ; Ukwatta et al., GCN 7894) \nwas detected by the Suzaku Wide-band  All-sky Monitor (WAM) which covers \nan energy range of 50 keV - 5 MeV at 10:25:28 UT on 23 July 2008 (=T0). \nThe observed light curve shows a multi-peaked structure starting at T0, \nending at T0+10 s with a duration (T90) of about 7 seconds. The fluence in \n100 - 1000 keV was (1.6 +/- 0.4) E-6 erg/cm^2. The 1-s peak flux measured \nfrom T0+ 8 s was 0.5 +/- 0.4 photons/cm^2/s in the same energy range.\n\nPreliminary result shows that the time-averaged spectrum from T0 to T0+10 s\nis well fitted by a single power-law with a photon index of 2.0 -0.9+1.0\n(chi^2/d.o.f =  5.6 / 8) at the 150 - 600 keV bandpass.\n----\n\nAll the quoted errors are at statistical 90% confidence level,\nin which the systematic uncertainties are not included.\n\n----\nThe light curves with 1-sec time resolution for this burst will be \nappeared at the following URL.\n http://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/untrig/grb_table.html\n\n[GCN OPS NOTE(30jun08): Per author's request, the Subject was changed\nfrom \"080523\" to \"080623\".]",
