Abstract:
This report includes classifications of one Type Ia, two Type II.

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 2020PASP..132h5002S).

Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2024 January 12, using EFOSC2 and Grisms 11 (3380-7520, 13.8A resolution) and 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.
