Abstract:
This report includes classifications of 4 Type Ia, 1 Type Ia-pec, 1 Type Ibc, 1 Type I, and 1 AGN.

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).

Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2021 February 1, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done using SNID (Blondin & Tonry 2007 2007ApJ...666.1024B), GELATO (Harutyunyan et al. 2008 2008A&A...488..383H), and a custom classification tool.

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.
