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 ) 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 2016-07-26, 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) Best fit with several type Ia such as SNe 2002er and 2002bo
(2) Spectroscopically similar to several type IIP SNe at the beginning of the plateau (Phase +7 to +20 after maximum)
