ePESSTO+, the advanced Public ESO Spectroscopic Survey for Transient Objects (see Smartt et al. 2015, A&A, 579, 40 ), reports the following supernova classifications. Targets were supplied by the Zwicky Transient Facility (; Kulkarni et al. 2018, ATel 11266) data stream processed through the Lasair broker (, by the All Sky Automated Survey for SuperNovae ASAS-SN (see Shappee et al. 2014, ApJ, 788, 48 and, and by the ATLAS survey, see Tonry et al. (2018, PASP, 130,  064505).
All observations were performed on the ESO New Technology Telescope at La Silla on 2019 June 10, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). Classification spectra and additional details can be obtained from WISeREP) and the IAU Transient Name Server.
