ePESSTO, the extended Public ESO Spectroscopic Survey for Transient Objects (see Smartt et al. 2015, A&A, 579, 40 http://www.pessto.org ),
reports the following supernova classifications. The targets were supplied by the ATLAS survey, see Tonry et al. (2011, PASP, 123, 58) and
Tonry et al. (ATel #8680) and the Zwicky Transient Facility (https://www.ztf.caltech.edu/; Kulkarni
et al. 2018, ATel 11266) data stream processed through the Lasair broker (http://lasair.roe.ac.uk/). Observations were performed on the ESO New Technology Telescope at La Silla on 2019-01-31, using EFOSC2 and Grism 13 (3685-9315, 21.2A resolution).
Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and GELATO (Harutyunyan et al.,
2008, A&A, 488, 383). Classification spectra and additional details can be obtained
from http://www.pessto.org (via WISeREP) and the IAU Transient Name Server.

(1) Best match with several Type Ia SNe around maximum light. The expansion velocity deduced from the Si II 635.5nm minimum is about 12800 km/s. The redshift of the host galaxy is from Jones et al. 2009, The 6dF Galaxy Survey Data Release 3 (via NED).
(2) Best match with several Type Ia SNe around maximum light. The expansion velocity deduced from the Si II 635.5nm minimum is about 11400 km/s. The redshift has been deduced from the SN spectral fitting.
(3) Best match with several Type Ia SNe around maximum light. The expansion velocity deduced from the Si II 635.5nm minimum is about 10600 km/s. The redshift has been deduced from the SN spectral fitting. ZTF19aacyqhc was observed as part of the GREAT survey (Chen et al. 2018, ApJ, 867L, 31), having a black body temperature of T_BB ~ 10800 +/- 1800 K obtained from the photometry taken on 29.01.2019 with griz= 19.56,19.49,19.85,20.27 mag.
(4) Best match with several Type Ia SNe around maximum light. The expansion velocity deduced from the Si II 635.5nm minimum is about 11100 km/s. The redshift has been deduced from the SN spectral fitting. ZTF19aaflnii was observed as part of the GREAT survey (Chen et al. 2018, ApJ, 867L, 31), having a black body temperature of T_BB ~ 11400 +/- 300 K obtained from the photometry taken on 29.01.2019 with griz= 19.32,19.44,19.57,19.73 mag.
(5) Best match with several Type Ic SNe about a week after maximum light. The expansion velocity deduced from the SiII 635.5nm minimum is about 8600 km/s. The redshift of the host galaxy is from Paturel et al. 2003, A&A 412, 57 (via NED).
(6) Best match with several Type Ia SNe around maximum light. The expansion velocity deduced from the Si II 635.5nm minimum is about 10600 km/s. The redshift of the host galaxy is from SDSS DR4, 2005 (via NED).
