We report spectroscopic classification by OzDES of a supernova discovered by the Dark Energy Survey (ATel #4668). The spectrum (370-885nm) was obtained with the AAOmega Spectrograph (Saunders et al. 2004, SPIE, 5492, 389) and the 2dF fibre positioner at the Anglo-Australian Telescope (AAT). Object classification was performed using superfit (Howell and Wang, 2002, BAAS, 34, 1256), the details of which are reported in the table below.

 DES13X3woy   | 02 24 28.72  | -04 58 02.3  | 2013 Dec 01  |  22.2      | 2013 Dec 26 | 0.31      | I       | -     | Matches a SN Ibc at maximum light or a Ia two weeks after max. 
The reduced spectrum has a number of artefacts that we hope to remove when we reprocess the data with a revised version of the 2dfdr pipeline.
