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), the OGLE-IV Transient Search (see Wyrzykowski et al., ATEL #4495), and the CATA Supernova Search (which is part of the Center of Astrophysics and Associated Technologies, CATA) with the 0.50-m CATA500 telescope located at Cerro Tololo. All observations were performed on the ESO New Technology Telescope at La Silla on the night starting 2013 Dec 10, 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) Broad, weak Halpha and Hbeta emission is seen on a blue continuum, consistent with a Type II SN a few days after explosion.
(2) Blue continuum with narrow emission lines at 4680, 7242, 8116 Ang, corresponding to MgII, Hgamma and Hbeta at z=0.67 respectively.
(3) Galaxy spectrum, redshift measured from narrow Halpha line.
