ePESSTO, the extended Public ESO Spectroscopic Survey for Transient Objects (see Smartt et al. 2015, A&A, 579, 40 http://www.pessto.org ), reports the following supernova classification. The target was supplied by Stuart Parker (BOSS). The observation was performed on the ESO New Technology Telescope at La Silla on 2017, Nov. 9, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). The classification was 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.
