Abstract:
This report includes classifications of three Type Ia's, two Type II's, one CV and AT2019oop which shows blue and featureless continuum which suggest core-collapse SN. AT2019oqq, AT2019onu and AT2019ovn were not visible on acquisition image.

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), 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) and the All Sky Automated Survey for SuperNovae ASAS-SN (see Shappee et al. 2014 2014ApJ...788...48S 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 August 28, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done using SNID (Blondin & Tonry 2007 2007ApJ...666.1024B) and GELATO (Harutyunyan et al. 2008 2008A&A...488..383H) and Superfit (Howell et al. 2005 2005ApJ...634.1190H).

The classification spectra and additional details can be obtained from http://www.pessto.org (via WISeREP) and the IAU Transient Name Server.
