PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see Valenti et al., ATel #4037; http://www.pessto.org ), reports the following supernova classifications. Targets were supplied by the La Silla-Quest survey (see Hadjiyska et al., ATel #3812) and the OGLE-IV Transient Search (see Wyrzykowski et al., ATEL #4495). All observations were performed on the ESO New Technology Telescope at La Silla on 2013 August 05 (UT), 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, ApJ, 634, 1190). Classification spectra can be obtained from http://www.pessto.org via WISeREP (Yaron & Gal-Yam, 2012, PASP, 124, 668).
