PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see Valenti et al., ATel #4037; http://www.pessto.org ),
reports the following supernova classifications. Targets were supplied by the Catalina Real-time Transient Survey (http://crts.caltech.edu/) and the Backyard Observatory Supernova Search (http://bosssupernova.com/). All observations were performed on the ESO New Technology Telescope at La Silla on 2013 Novembre 3, 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).
