We report on a Suzaku ToO observation of the new soft gamma-ray repeater SGR 0501+4516 (Holland et al. GCN #8112, Barthelmy et al. GCN #8113), started on 2008-08-26 00:05 UT, for an exposure time of about 43 ksec (Mitsuda et al. GCN #8136). A bright point source was clearly detected in the XIS CCDs at a position consistent with that of SGR 0501+4516 (Evans et al. GCN #8148). From a preliminary analysis of the XIS data, the 1-10 keV persistent emission spectrum is well fit by a black body with a temperature of 0.7 keV, plus a power-law with a photon index of 2.9, absorbed by a hydrogen column density of 1.0x10^22 cm^-2.
