This report includes classifications of 5 Type Ia supernovae, 2 Type II supernovae, 2 objects with a blue continuum, and 1 object dominated by galaxy flux.

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 Pan-STARRS Survey for Transients (Chambers et al. 2016 2016arXiv161205560C), the ATLAS survey (Tonry et al. 2018 2018PASP..130f4505T) and, 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 July 28, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done using SNID (Blondin & Tonry 2007 2007ApJ...666.1024B) and Superfit (Howell et al. 2005 2005ApJ...634.1190H).

The classification spectra and additional details can be obtained from (via WISeREP) and the IAU Transient Name Server.

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