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 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 ATLAS survey, see Tonry et al. (2011, PASP, 123, 58) and Tonry et al. (ATel #8680). All observations were performed on the ESO New Technology Telescope at La Silla on 2018 Dec 29, 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) No source found at the reported position.
(2) Spectrum shows strong contribution of host galaxy.
(3) Early spectroscopy of this object was reported by Kilpatrick and Foley (ATel #12339).
(4) Redshift derived from SNID
(5) Spectrum shows blue continuum with three broad (FWHM is around 30 000 km/s) emission features around 4200, 4700 and 5500 A. We did not find reasonable template match. Redshift is unknown. Discovery was also reported by ATLAS.
