Abstract:
This report includes classifications of four Type Ia's and one Type II.

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 (Tonry et al. 2018 2018PASP..130f4505T), and OGLE-IV Real-time Transient Search (Wyrzykowski et al., 2014 arxiv:1409.1095http://ogle.astrouw.edu.pl/).

Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2019 Dec 06, 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) and Astrodash (Muthukrishna et al. 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.
