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 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 ), the OGLE-IV Real-time Transient Search (Wyrzykowski et al., 2014 arxiv:1409.1095; http://ogle.astrouw.edu.pl/ ) and by the Pan-STARRS Survey for Transients (see Huber et al., ATel #7153). We acknowledge ESA Gaia, DPAC and the Photometric Science Alerts Team (http://gsaweb.ast.cam.ac.uk/alerts). All observations were performed on the ESO New Technology Telescope at La Silla on 2016-07-25, using EFOSC2 and Grism 13 (3985-9315A, 28A 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).

(2) Weak and unresolved Halpha and OIII lines at z=0.023. Blue, featureless spectrum. The transient would be around -17.9, consistent with a young CC-SNe.
(3) Featureless blue spectrum with Balmer absorption at z~0. 6" from a galaxy detected in PS1. Most likely a CV
