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:1409.1095

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 (via WISeREP) and the IAU Transient Name Server.

The classified objects are listed in the Related Objects table below.
