We report optical spectroscopy of DES15E1iuh discovered by the Dark Energy Survey. We obtained spectra using the X-SHOOTER instrument (wavelength range 380-950nm) on the Very Large Telescope (VLT) of the European Southern Observatory (ESO) and the AAOmega Spectrograph (Saunders et al. 2004, SPIE, 5492, 389; wavelength range 370-885nm) and the 2dF fibre positioner at the Anglo-Australian Telescope (AAT). 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.

a). Redshift from galaxy emission features  
b). Phases given relative to the VLT spectrum. The phase estimated from the AAT spectrum is consistent.
