PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see Smartt et al. 2015, A&A, 579, 40 http://www.pessto.org ), reports the following supernova classifications. Targets were supplied by Pan-STARRS Survey for Transients (see Huber et al., ATel #7153), All Sky Automated Survey for SuperNovae ASAS-SN (see Shappee et al. 2014, ApJ, 788, 48 and http://www.astronomy.ohio-state.edu/~assassin/index.shtml ), OGLE-IV Real-time Transient Search (Wyrzykowski et al., 2014 arxiv:1409.1095; http://ogle.astrouw.edu.pl/ ) and from CRTS (Drake et al. 2009, 696, 870 ; http://crts.caltech.edu/ ). All observations were performed on the ESO New Technology Telescope at La Silla on 2015 December 31, 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).

Notes
(1) Target not visible in acquisition image
(2) Spectrum dominated by host galaxy light - no SN signal to enable identification.
(3) As well as narrow H-alpha emission, base of the feature is broad. Also shows strong broad H-beta.
(4) Appears to be a very young object. H-alpha and H-beta absorption show evidence of two velocity components. Otherwise spectrum is blue and relatively featureless
