We report the following spectroscopic classification of two supernovae based on observations 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). Targets were discovered by Stu Parker (TOCP) and the ASAS-SN survey (see Stanek et al., ATel #5193). Both targets were observed for 40 minutes on 2013 July 04 UT. Classifications were done using SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

(1) Good match to SN 2005cs at 30 days and z=0.019. Consistent with redshift of apparent host PGC 5154 (z=0.020174; Theureau et al., 1998, A&AS, 130, 333).

(2) Good match with SN 2002er at -1 days and z=0.015. Consistent with redshift of apparent host UGC 01395 (z=0.017405; Mahdavi & Gellar, 2004, ApJ, 607, 202).
