PESSTO, the Public ESO Spectroscopic Survey for Transient The 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 Catalina Real-time Transient Survey (http://crts.caltech.edu/). All observations were performed on the ESO New Technology Telescope at La Silla on 2012 December 05, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution), except for LSQ12gdj which was observed with Grisms 11 (3380-7520A, 13A resolution) and 16 (6010-10330A, 13A reolution). 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).
