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 were supplied by the ATLAS survey (see Tonry et al., 2011, PASP, 123, 58), and 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/). All observations were performed on the ESO New Technology Telescope at La Silla on 2018 December 8, 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.

(1) Spectrum shows Balmer, Helium and possibly Calcium emission lines consistent with redshift 0, and also exhibits some excess continuum flux in the red. SDSS shows an extended red object at the location of the source, possibily an extended nebula.
