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 the ATLAS survey, see Tonry et al. (2011, PASP, 123, 58) and Tonry et al. (ATel #8680), and by the 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 ) All observations were performed on the ESO New Technology Telescope at La Silla on 2016 November 04, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). The classification was done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). Classification spectrum and additional details can be obtained from http://www.pessto.org (via WISeREP) and the IAU Transient Name Server.

(1) Host galaxy redshift taken from NASA/IPAC Extragalactic Database (NED).
(2) Host galaxy redshift taken from NED. Assuming the host galaxy redshift and the Galactic line-of-sight reddening from NED, the SN appears to be a faint SN Ia with M_V = -18.3.
