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 OGLE-IV Real-time Transient Search (Wyrzykowski et al., 2014 arxiv:1409.1095; http://ogle.astrouw.edu.pl/ ) and La Silla-Quest survey (see Baltay et al., PASP, 2013, 125, 683). All observations were performed on the ESO New Technology Telescope at La Silla on 2015 April 18, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). Classification spectra can be obtained from http://www.pessto.org (via WISeREP).
