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 was supplied by the Catalina Real-time Transient Survey (http://crts.caltech.edu/).
The observation was performed on the ESO New Technology Telescope at La Silla on 2013 September 07 (UT), 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 (Yaron & Gal-Yam, 2012, PASP, 124, 668).
