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 CHASE, the La Silla-Quest survey (see Hadjiyska et al., ATel #3812), Pan-STARRS1 (www.ps1sc.org), 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 2013 October 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).
