Abstract:
This report includes classifications of one Type Ia supernovae, and one other. AT2019uzg is a star forming galaxy with z=0.0532.

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 the Zwicky Transient Facility ZTF (Kulkarni 2018 2018ATel11266....1K) - 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 May 13, 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.
