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 OGLE-IV (ATel #4495; Wyrzykowski et al. 2012). All observations were performed on the ESO New Technology Telescope at La Silla on 2014 Jan 02, 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) No galactic emission line is visible for a precise redshift estimate.
(2) Blue featureless continuum. Unlikely extra-galactic object.
(3) Good match to 2007bi and PTF12dam at +55d. Absolute mag M_v ~ -20, in accordance with these SLSNe at 50 days past peak.
(4) Featureless low signal to noise spectrum. Likely faded since last CRTS detection. Possible break around 4100A.
