Abstract:
This report includes classifications of 3 Type Ia supernovae, I Type IIP, and one other. AT2019qip has a red, mainly featureless continuum. Two targets, AT2019vdf and AT2019uyy were not visible in 15 and 10 s acquisition image, respectively.

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), 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 Nov 19, 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.

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