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. The targets were supplied by the ATLAS survey, see Tonry et al. (2011, PASP, 123, 58) and Tonry et al. (ATel #8680), by the ESA Gaia Photometric Science Alerts Team and DPAC ( http://gsaweb.ast.cam.ac.uk/alerts ) and by Pan-STARRS Survey for Transients (see Chambers et al. 2016, arXiv:1612.05560, and http://pswww.ifa.hawaii.edu ). The observations were performed on the ESO New Technology Telescope at La Silla on 2017 February 4, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). 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.
