PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see Smartt et al. 2014, arXiv:1411.0299; http://www.pessto.org ), reports the following supernova classifications. Targets were supplied by LSQ (Baltay et al. 2013, PASP, 125, 683), the OGLE-IV Real-time Transient Search (Wyrzykowski et al. 2014, arxiv:1409.1095; http://ogle.astrouw.edu.pl ), and CRTS (Drake et al. 2009, ApJ, 696, 870; http://crts.caltech.edu/ ). All observations were performed on the ESO New Technology Telescope at La Silla on 2015-01-26, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and GELATO (Harutyunyan et al. 2008, A&A, 488, 383). Classification spectra can be obtained from http://www.pessto.org (via WISeREP).
