We report spectroscopic classification of PSN J06234727-6519484 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 J06234727-6519484 was discovered by Parker on 2013 Nov 13.61 at mag 17.9 in PGC 75726. A 40 minute spectrum of the SN on 2013 Nov 14.70 shows this object to be a type Ia supernova about 10 days after maximum light. Si 6355, Ca H/K and the IR triplet, P-Cygni "Na" (which may instead be Co - see Dessart arXiv:1310:7750), and Fe lines around 5000 AA are all evident. Classification with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) shows good match to SN 2002ej at +10 days and SN 2003cg at +12 days. Preferred redshift from SNID is about 0.033 +- 0.005, consistent with the redshift of the apparent host galaxy which we measured at z = 0.0301 from narrow Halpha emission.
