Abstract:
This report includes classification of 1 AGN and 1 Type II SN. We encourage follow-up observations.

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 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 2025 January 08, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done using SNID (Blondin & Tonry 2007 2007ApJ...666.1024B), and GELATO (Harutyunyan et al. 2008 2008A&A...488..383H).

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.
