Abstract:
This report includes classification of SN 2019vrd as supernova Type Ia around week before maximum.

ePESSTO+, the advanced Public ESO Spectroscopic Survey for Transient Objects (Smartt et al. 2015 2015A&A...579A..40S), reports the following supernova classifications.

Target was supplied by the ATLAS survey (Tonry et al. 2018 2018PASP..130f4505T).

Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2019 November 27, 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.
