Abstract:
This report includes classifications of 1 Type Ia SN and 1 CV.

ePESSTO+, the extended 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 ESA Gaia Photometric Science Alerts Team DPAC and the DLT40 Survey

Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2019 July 24, 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.
