We report optical spectroscopy of DES15S2lam discovered by the Dark Energy Survey. The spectrum (540-965nm) was obtained using GMOS on Gemini-North. 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.
