PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see Smartt et al., arXiv:1411.0299 http://www.pessto.org ), reports the following supernova classifications. Targets were supplied by the La Silla-Quest survey (see Baltay et al., PASP, 2013, 125, 683), and SkyMapper (Scalzo et al., ATel #5480). All observations were performed on the ESO New Technology Telescope at La Silla on 2015-03-19, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and superfit (Howell et al. 2005, Ap.J. 634, 1190). Classification spectra can be obtained from http://www.pessto.org (via WISeREP).
