Abstract:
This report includes classifications of 6 Type Ia SNe and one narrow lined transient (AT2023adr)

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), and 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 April 09, using EFOSC2 and Grisms 11 (3380-7520, 13.8A resolution) and 13 (3985-9315A, 18A resolution). Classifications were done using GELATO (Harutyunyan et al. 2008 2008A&A...488..383H), Superfit (Howell et al. 2005 2005ApJ...634.1190H) and DASH (Muthukrishna, Parkinson and Tucker, 2019 2019ApJ...885...85M)

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.
