Abstract:
This report includes classifications of 3 Type Ia's, 1 Type II. 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 the Pan-STARRS Survey for Transients (Chambers et al. 2016 2016arXiv161205560C), the ATLAS survey (Smith et al. 2020 2020PASP..132h5002S), the Zwicky Transient Facility ZTF (Bellm et al. 2019 2019PASP..131a8002B) - data stream processed through the Lasair broker (Smith, Williams, Young et al. 2019 2019RNAAS...3...26S) and by the ALeRCE broker (Forster et al. 2020 2021AJ....161..242F), the All Sky Automated Survey for SuperNovae ASAS-SN (see Shappee et al. 2014 2014ApJ...788...48S), the PMO-Tsinghua Transient Survey PTSS, the Gravitational-wave Optical Transient Observer GOTO (see Dyer et al. 2020, SPIE, 11445 2020SPIE11445E..7GD) and by the ESA Gaia Photometric Science Alerts Team DPAC.

Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2024 August 27, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done using SNID (Blondin & Tonry 2007 2007ApJ...666.1024B), GELATO (Harutyunyan et al. 2008 2008A&A...488..383H), Astrodash (Muthukrishna 2019 2019ApJ...885...85M and NGSF (Next Generation SuperFit; AstroNote 2022-191, Howell et al. 2005 2005ApJ...634.1190H).

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.
