We report optical spectroscopy of a supernova (SN) candidate discovered by the Dark Energy Survey (ATel #4668). The spectrum (400-900 nm) of DES13C1feu was obtained using the Robert Stobie Spectrograph (RSS) on the Southern African Large Telescope (SALT). A fit of the spectrum with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) reveals this event to be a type Ic supernova at z=0.06 at peak brightness. This redshift is confirmed by emission features from the host galaxy at z=0.059. The phase at the date of the spectrum given below is based on the DES light curves.
