Abstract:
{{e.g. This report includes classifications of 2 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 All Sky Automated Survey for SuperNovae ASAS-SN (see Shappee et al. 2014 2014ApJ...788...48S), 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 2021 Dec 05, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done using SNID (Blondin & Tonry 2007 2007ApJ...666.1024B) and GELATO (Harutyunyan et al. 2008 2008A&A...488..383H) and Superfit (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.
