PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see Smartt et al., arXiv:1411.0299 http://www.pessto.org ), reports the following supernova classifications. Targets were supplied by the La Silla Quest survey (LSQ) (Baltay et al. 2013, PASP, 125, 683), the OGLE-IV Real-time Transient Search (Wyrzykowski et al., 2014 arxiv:1409.1095; http://ogle.astrouw.edu.pl/ ), MASTER Robotic Net (Gorbovskoy et al. 2013, ARep, 57, 233; http://observ.pereplet.ru ) and the IAU Transient Objects Confirmation Page (TOCP). All observations were performed on the ESO New Technology Telescope at La Silla on 2015-02-11, 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) Blue continuum, Hydrogen Balmer absorption lines at zero redshift. Likely galactic variable
(2) Match 05cc +5d to +10d and 02cx +10d. Most likely associated with NGC 3464
(3) Best match with type IIP sn2004et post max
(4) Good match to sn2004eo +3d
(5) Match type IIP sn2004et +6d
(6) As in ATel #7052, a good match to type IIP SN199em around phase +6d and SN2004et at +9d. To clarify, the ambiguity in ATel #7052, the redshift of this SN is z=0.026
