We report spectroscopic classification of two ASAS-SN transients 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). Discovery and classification information are found in the table below, targets were observed on 2015 Mar 06, and classifications were made with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
