Referred to by ATel #: 8954

We report optical spectroscopy of 17 supernovae discovered by the Dark Energy Survey (ATel #4668). The spectra (380-820nm) were obtained using the Robert Stobie Spectrograph (RSS) on the South African Large Telescope (SALT). 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.
