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 the Catalina Real-time Transient Survey (http://crts.caltech.edu/). All observations were performed
on the ESO New Technology Telescope at La Silla on 2012 October 08, 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).

(1) Flat continuum, broad features between 4000A and 7000A. Ha and Hb emission (no P-Cygni profile) visible at the rest
wavelength (z=0.148). Possible Type Ic SN after peak. A host galaxy is visible in the reference image but it is not in the NED
(http://ned.ipac.caltech.edu) archive.
