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/). Observations were performed on the ESO New Technology Telescope at La Silla on 2012 September 07 (SSS120817:002822-305723) and 2012 September 09 (SSS120816:012937-175040), using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done with 'superfit' (Howell et al. 2005). Classification spectra can be obtained from http://www.pessto.org (via WISeREP).
