Abstract:
This report includes a classification of one young SN previously classified as Type II SN.

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 2020PASP..132h5002S).

Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2024 Dec 24, using EFOSC2 and Grism 11 (3380-7520 Å, 18A resolution).

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.
