Abstract:
This report includes classifications of one SN II (SN2019yhq), and one SN Ib (SN2019yvr) around maximum brightness. SN2019yvr is a nearby SN, located in the galaxy NGC 4666 (26 Mpc).

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 Pan-STARRS Survey for Transients (Chambers et al. 2016 2016arXiv161205560C), and 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 December 28, 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.

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