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 La Silla Quest Variability Survey (see Baltay et al. 2013, PASP, 125, 683), ESA Gaia, DPAC and the Photometric Science Alerts Team (http://gsaweb.ast.cam.ac.uk/alertsc), 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 2016 February 24th, 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) and the Transient Name Server.

a. Noisy spectrum. It has a blue and relatively featureless continuum, with a weak and narrow resolved Halpha emission line.
b. Discovered originally as LSQ16sy.
