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 Catalina Real-time Transient Survey (http://crts.caltech.edu/), and the OGLE-IV Transient Search (see Wyrzykowski et al., ATEL #4495). All observations were performed on the ESO New Technology Telescope at La Silla in the night starting on 2013 December 9 UT, 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) Good match to SN 2006gr.
(2) Reasonable match to SN 2008D at +6d.
(3) Blue continuum, Halpha in emission, other Balmer lines in absorption, z=0. Possible CV.
(4) Peculiar SN IIn or SN Ia-CSM. Good match to SNe 1997cy and 2005gj around 100d.
