We report spectroscopic classification of PSN 19493251-7013200 with the Wide Field Spectrograph (WiFeS - Dopita et al., 2007, ApSS, 310, 255) on the ANU 2.3m telescope at Siding Spring Observatory, NSW Australia, using the B3000/R3000 gratings (3500-9800 A, 1 A resolution). PSN 19493251-7013200 was discovered by Stu Parker (Backyard Observatory Supernova Search) on 2013 May 07.6 at mag 17.9. A 40 minute spectrum of the SN shows clear P-Cygni H-alpha absorption, as well as Hbeta, the Ca II IR triplet, Fe II 5018 and Fe II 5169. Classification with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) shows good matches to SN 2005cs at +13 days, SN 2004et at +20 days, and SN 2006bp at +20 days. Mean redshift from SNID is about 0.015, consistent with the redshift of the apparent host galaxy IC 4892 (z=0.013733 - Mathewson, Ford, & Buchhorn, 1992, ApJS, 81, 413).
