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 La Silla-Quest survey (see Hadjiyska et al.,
ATel #3812) and via the IAU Transient Objects Confirmation Page. All observations were performed
on the ESO New Technology Telescope at La Silla on 2012 September 16, 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).
