Abstract:
This report includes classifications of seven Type Ia's, one of them is Type Ia-91T, two Type II's., one Type Ic. AT2019ovu reminds of spectrum of 2008ha-like SN, superimposed by host emission lines. Two targets, AT2019pky and AT2019pal were not visible in 10 and 20 s acquisition image, respectively. We encourage followup observations.

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 All Sky Automated Survey for SuperNovae ASAS-SN (see Shappee et al. 2014 2014ApJ...788...48S), the ESA Gaia Photometric Science Alerts Team DPAC and OGLE-IV Real-time Transient Search (Wyrzykowski et al., 2014 arxiv:1409.1095; http://ogle.astrouw.edu.pl/).

Observations were performed on the ESO New Technology Telescope (NTT) at La Silla on the night of 2019 September 6, 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).

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.
