Abstract:
This report includes classifications of 5 Type Ia SNe.

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 Pan-STARRS Survey for Transients (Chambers et al. 2016 2016arXiv161205560C), the ATLAS survey (Smith et al. 2020 2020PASP..132h5002S) and 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 2021AJ....161..242F).

Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2023-12-14, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution) or Grism 11 (3380-7520, 16A 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.
