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 the OGLE-IV Real-time Transient Search (Wyrzykowski et al., 2014 arxiv:1409.1095 http://ogle.astrouw.edu.pl/ ). All observations were performed on the ESO New Technology Telescope at La Silla on 2014-11-22, 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).
