Abstract:
This report includes classifications of two Type Ia's and one Type II. SN2019vqd is a young Type II with a blue continuum, showing prominent flash features (Balmer, HeII 4686, NIII 4640, maybe CIV 5801).

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 the All Sky Automated Survey for SuperNovae ASAS-SN (see Shappee et al. 2014, ApJ, 788, 48 and http://www.astronomy.ohio-state.edu/~assassin/index.shtml).

Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2019 Nov 26, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done using SNID (Blondin & Tonry 2007 2007ApJ...666.1024B) 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.
