We report optical spectroscopy of DES15S2myz and DES15S2mwz discovered by the Dark Energy Survey (ATel #4668). The spectra (495-920nm) were obtained using OSIRIS on the Gran Telescopio CANARIAS (GTC). Object classification was performed using SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and superfit (Howell et al, 2005, ApJ, 634, 119), the details of which are reported in the table below.
