Abstract:
This report includes classifications of ATLAS20best as Supernova Type Ia at maximum.

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

Target was 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 2020 Oct 28, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done using SNID (Blondin & Tonry 2007 2007ApJ...666.1024B).

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

The classified object is listed in the Related Objects table below.
