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) and ESA Gaia, DPAC and the Photometric Science Alerts Team (http://gsaweb.ast.cam.ac.uk/alertsc). All observations were performed on the ESO New Technology Telescope at La Silla on 2016 February 15th, 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. Discovered originally as PS16tw.
b. Discovered originally as PS16ago. Spectrum is relatively blue, showing clear narrow + intermediate components of Balmer lines. A good match is found with the type IIn SN 2010jl at ~25 days after the discovery.
