Sakamoto (GSFC/UMBC), and K. Hurley (U.C. Berkeley),\non behalf of the Suzaku SGR ToO team, report:\n\nWe report on a Suzaku ToO observation of the new soft gamma-ray\nrepeater SGR 0501+4516 (Holland et al. GCN #8112, Barthelmy et al.\nGCN #8113), started on 2008-08-26 00:05 UT, for an exposure time of\nabout 43 ksec (Mitsuda et al. GCN #8136). A bright point source was\nclearly detected in the XIS CCDs at a position consistent with that of\nSGR 0501+4516 (Evans et al. GCN #8148).\n\nFrom a preliminary analysis of the XIS data, the 1-10 keV persistent\nemission spectrum is well fit by a black body with a temperature of \n0.7 keV, plus a power-law with a photon index of 2.9, absorbed by a \nhydrogen column density of 1.0x10^22 cm^-2. The absorbed 1-10 keV flux \nwas (3.7+/-0.1)x10^-11 erg/cm^2/s. The XIS data confirm the source\npulsations at a period of P = 5.762 +/- 0.001 s, consistent with the\nperiodicity derived by the RXTE/PCA (Gogus et al. GCN #8118),\nSwift/XRT (Mangano et al. GCN #8146), and XMM-Newton (Rea et al. Atel\n#1688; Israel et al. Atel #1692)\n\nAt least 16 short bursts were detected during the observation.\nThe largest burst was observed on 2008-08-26 03:16:16 by all Suzaku's\ninstruments including Suzaku-WAM, up to an energy of ~200 keV. The HXD \nspectral analysis of the persistent and burst emission is in progress.\n\nWe would like to thank the Suzaku managers and the operation team\nfor approving and carrying out the ToO observation.",
