Hong (Nihon U.), on behalf of the Suzaku WAM team, report:\n\nThe long GRB 100707A (Fermi/GBM trigger #300156400; C. Wilson-Hodge et al.,\nGCN 10944; Fermi-LAT detection; V. Pelassa et al., GCN 10945)\ntriggered the Suzaku Wide-band All-sky Monitor (WAM) which covers an\nenergy of 50 keV - 5 MeV at 2010-07-07 00:46:38.91 UT (T=0).\n\nThe observed light curve shows a FRED-like peak structure lasting from\nT0-0.5s to T0+18.5s with T90 of about 12 seconds. The fluence in 100 -\n1000 keV was 5.26 (+/-0.27) x 10^-5 erg/cm^2. The 1-s peak flux\nmeasured from T0+1.5s was 32.24 (-1.28, +1.22) photons/cm^2/s in the\nsame energy range.\n\nPreliminary result shows that the time-averaged spectrum from T0-0.5s\nto T0+18.5s is well fitted by a single power-law with a photon index\nof 2.15 (-0.05, +0.06) (chi^2/d.o.f = 39.4/25).\n\nDue to the brightness of this burst, a 3% systematic error was added\nfor low energy channels.  In addition, there might be some calibration\nuncertainties in these spectral parameters because GRB photons came to\nthe WAM detector by passing through the large Ne dewar of the X-ray\nmicro-calorimeter (XRS).\nAll the errors are quoted at 90% confidence level.\n\nThe light curves for this burst wiil be available at:\nhttp://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html",
