We report optical spectroscopy by the OzDES collaboration of a supernova candidate discovered by the Dark Energy Supernova Survey (ATel #4668). The spectrum (350-900 nm) of DES12C3a was obtained at the Anglo-Australian Telescope with AAOmega-2dF observed by A. Hopkins. SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) shows this event to be a Type Ia SN at z=0.24 near maximum light.
