Abstract:
This report includes classifications of 4 SNe Ia and 1 SN 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 2020arXiv200309052S) and by All Sky Automated Survey for SuperNovae ASAS-SN (Shappee et al. 2014, ApJ, 788, 48)

Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2022 January 10, using EFOSC2 and Grism 13 (3650-9250 A, resolution 17 A). Classifications were done using 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.
