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 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), BlackGEM, and by the Gravitational-wave Optical Transient Observer GOTO (see Dyer et al. 2020, SPIE, 11445 2020SPIE11445E..7GD).
Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2024 Nov 11, using EFOSC2 with Grism 13 (3985-9315A, 18A resolution) and Grism 11 (3380-7520, 16A resolution). Classifications were done using SNID (Blondin & Tonry 2007 2007ApJ...666.1024B) 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.
