Hara (Univ. of Miyazaki), \nM. Kokubun, M. Suzuki, T. Takahashi (ISAS/JAXA), S. Hong (Nihon U.), \non behalf of the Suzaku WAM team, report:\n\nThe long burst, GRB 070626 (S. Golenetskii et al. GCN 6592) was\ndetected at 2007-06-26 04:07:30 UT (= T0) with the Suzaku Wide-band All-sky\nMonitor (WAM), which covers an energy range of 50 keV - 5 MeV. The burst\ncontinues from T= T0-120 sec to T0+210 sec, as already reported on GCN\n6592. The object position reported by GCN 6592 corresponds to the\nincident angle of (theta, phi) = (103 deg, 169 deg) to the HXD WAM,\nwhere the energy response is well calibrated. \nThe fluence in the 100 -- 1000 keV energy band was 2.25(+- 0.01) x\n10^-4 erg/cm2, and the 1-sec peak flux was 19.5 +/- 0.2 photons/cm^2/sec \nin the same energy range.\n\nAccording to preliminary analyses, the time averaged spectrum from T0\nto T0+190 sec in the 120 keV to 2.0 MeV energy band can be reproduced by \nthe Band function (Band et al. 1993, ApJ 413, p281) with the following \nparameters;\n  alpha = -1.55 +/- 0.05, \n  beta  = -2.15 +/- 0.05, and\n  Epeak =   600 +/- 50 keV.\n\nAll the quoted errors are at the 90% confidence level, while systematic \nerrors are not included. Since the on-board trigger system was disabled \nat the time of T0, no BST mode data with a time resolution of 15.625\nmsec is available, and the spectral analyses were performed by the \ncontinuous monitoring (TRN) data with the 1 sec resolution.\n\nThe light curve data with 1 sec resolution will be appeared at the web site \n http://www.astro.isas.ac.jp/suzaku/HXD-WAM/WAM-GRB/grb/untrig/grb_table.html",
