Abstract:
This report includes classification of one Type Ia supernovae.

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) - data stream processed through the Lasair broker (Smith, Williams, Young et al. 2019 2019RNAAS...3a..26S)

Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2019 Nov 22, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done using SNID (Blondin & Tonry 2007 2007ApJ...666.1024B) .

The classification spectra and additional details can be obtained from http://www.pessto.org (via WISeREP) and the IAU Transient Name Server. Targets were supplied by the ATLAS survey, see Tonry et al. (2018, PASP, 130,  064505)

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