ePESSTO+, the advanced 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 the Zwicky Transient Facility (https://www.ztf.caltech.edu/; Kulkarni et al. 2018, ATel 11266) data stream processed through the Lasair broker http://lasair.roe.ac.uk/, by the ATLAS survey, see Tonry et al. (2018, PASP, 130, 064505) and by the All Sky Automated Survey for SuperNovae ASAS-SN (see Shappee et al. 2014, ApJ, 788, 48 and http://www.astronomy.ohio-state.edu/~assassin/index.shtml ). All observations were performed on the ESO New Technology Telescope at La Silla on 2019 May 23, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and superfit (Howell et al. 2005, Ap.J. 634, 1190). Classification spectra and additional details can be obtained from http://www.pessto.org (via WISeREP) and the IAU Transient Name Server.

(1) Redshift from narrow emission lines.
(2) Spectrum consists of blue continuum with strong Balmer emission lines.
(3) Observed as part of the GREAT survey (Chen et al. 2018, ApJ, 867L, 31) on 2019 May 22, with photometric measurements of griz= 18.85,18.87,18.8,18.97 mag (against GROND zero points). This is well fit to a black body temperature of T_BB > 9000 +/- 600 K.
(4) Redshift from SNID fit.
(5) Observed as part of the GREAT survey (Chen et al. 2018, ApJ, 867L, 31) on 2019 May 23, with photometric measurements of griz= 18.42,18.26,18.92,19.07 mag. This is well fit to a black body temperature of T_BB > 12000 +/- 3600 K.
