We report optical spectroscopy of DES15C2kyh discovered by the Dark Energy Survey. The spectrum (340-1025nm) was obtained using LRIS on Keck-I. Object classification was performed using superfit (Howell et al, 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry, 2007, ApJ, 666, 1024), the details of which are reported in the table below.
