Abstract:
This report includes classifications of 2 Type Ia, 2 Type II, 1 Type SLSN-IIn. SN2020abtf shows a blue continuum with a bump at around ~4700A, which we associated to CIV 4648A. We classified it as a young SNII.

ePESSTO+, the advanced Public ESO Spectroscopic Survey for Transient Objects (Smartt et al. 2015 2015A&A...579A..40S), reports the following supernova classifications.

Targets were supplied by the ATLAS survey (Smith et al. 2020 2020arXiv200309052S), and the Zwicky Transient Facility ZTF (Bellm et al. 2019 2019PASP..131a8002B).

Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2020 December 6, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done using SNID (Blondin & Tonry 2007 2007ApJ...666.1024B).

The classification spectra and additional details can be obtained from http://www.pessto.org (via WISeREP) and the IAU Transient Name Server.

The classified objects are listed in the Related Objects table below.
