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), from the Catalina Real-time Transient Survey (CRTS; Drake et al. 2009, ApJ, 696, 870 ; http://crts.caltech.edu/ ), and from the IAU TNS list (see https://wis-tns.weizmann.ac.il/) All observations were performed on the ESO New Technology Telescope at La Silla on 2016 September 29th, 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 and additional details can be obtained from http://www.pessto.org (via WISeREP) and the IAU Transient Name Server.

(1) SNID matches several normal SNe Ia around maximum light
(2) Spectrum is dominated by host galaxy light
(3) SNID finds the spectrum matches several Type Ic SNe at peak at z = 0.06 +- 0.007
(4) SNID best matches SN 1992H at ~+100 days
(5) SNID matches several Type II SNe approximately two weeks after maximum light
