Abstract:
This report includes 8 classifications: 2 SNe Ib/c, 2 SNe Ia, 1 Galactic transient, 2 SNe II and 1 SN IIn.

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), by the ESA Gaia Photometric Science Alerts Team DPAC and by the Zwicky Transient Facility ZTF (Bellm et al. 2019 2019PASP..131a8002B) - data stream processed through the Lasair broker (Smith et al. 2019 2019RNAAS...3a..26S), and by the ALeRCE broker (Forster et al. 2020 https://arxiv.org/abs/2008.03303).

Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2022 January 22, 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.
