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. The targets were supplied by the ATLAS survey, see Tonry et al. (2018, PASP, 130, 064505), 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/), 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 ) and the ESA Gaia Photometric Science Alerts Team and DPAC (http://gsaweb.ast.cam.ac.uk/alerts). All observations were performed on the ESO New Technology Telescope at La Silla on 2019-05-13, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024), GELATO (Harutyunyan et al., 2008, A&A, 488, 383)and Superfit (Howell et al. 2005, ApJ, 634, 1190). Classification spectra and additional details can be obtained from http://www.pessto.org (via WISeREP) and the IAU Transient Name Server.

(1) Location consistent with MASIV J2113+1121
(2) Matches classification reported in TNS Classification Report No. 4067
(3) Redshift obtained from template fitting. The redshift from the fit approximately matches the host galaxy photo-z.
(4) Redshift obtained from best fitting template.
(5) Spectrum shows a close match to SN 2005gj
(6) Redshift obtained from the host galaxy.
