We report optical spectroscopy of a supernova candidate discovered by the Dark Energy Survey (ATel #4668). The spectrum (400-850nm) of DES15C2ir was obtained using the Robert Stobie Spectrograph (RSS) on the Southern African Large Telescope (SALT). Classification was performed using SNID (Blondin & Tonry, 2007, ApJ, 666, 1024), revealing this event to be a type Ia supernova at z=0.058, 3 days after maximum light.
