Abstract:
This report includes classification of one Type Ia SN

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

The 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 2023 Sept 17, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classification was done using GELATO (Harutyunyan et al. 2008 2008A&A...488..383H); and the redshift is determined from the SN spectrum.

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.
