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 30, 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) Redshift derived from SNID
(2) Redshift derived from SNID. Object shows very quick spectral evolution from day to day. Early spectroscopy of this object was reported by Razza et al. (ATel #12342).
(3) No source found at the reported position.
(4) Spectrum match very well with templates of SN 2004et in various phase. Phase is estimated base on ATLAS light curve.
(5) No source found at the reported position.
(6) Redshift derived from SNID
(7) Spectrum is typical for a young SN type II and shows broad and shallow H-alpha and H-beta at the redshift of the host (z = 0.027) superimposed on blue continuum.
