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 classifications. Targets are from the ESA Gaia Photometric Science Alerts Team and DPAC (http://gsaweb.ast.cam.ac.uk/alerts), and MASTER (see http://observ.pereplet.ru/ ; Lipunov et al. 2004, AN, 325, 580). All observations were performed on the ESO New Technology Telescope at La Silla on 2018 Dec 15, 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.

a. Source exhibits a blue continuum with narrow emission lines consistent with Helium emission at z=0.036. The best matches are to
SN2011hw at 16days from discovery. This source was detected by MASTER 8 days previously.
