PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see Valenti et al., ATel #4037; http://www.pessto.org ), reports the following supernova classifications. Most targets were supplied by the La Silla-Quest survey (see Hadjiyska et al., ATel #3812). SNhunt119 was discovered by S. Howerton in course of the Supernova Hunt project (http://nesssi.cacr.caltech.edu/catalina/current.html). All observations were performed on the ESO New Technology Telescope at La Silla on 2012 April 11 and 12, 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 WISEASS).
