We report spectroscopic classification of optical 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 2014 Apr 02. The PS1 targets were provided from the 3Pi survey operated by the Pan-STARRS1 Science Consortium (http://ps1sc.org) and made public via http://star.pst.qub.ac.uk/ps1threepi/ (see Smartt et al. ATel #5850 and Inserra et al. 2013, ApJ, 770, 128 for a description of the 3Pi survey). Classifications were made with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
