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. Targets were supplied by the ATLAS survey, see Tonry et al. (2011, PASP, 123, 58) and Tonry et al. (ATel #8680), and the Pan-STARRS Survey for Transients (see Chambers et al. 2016, arXiv:1612.05560, and http://pswww.ifa.hawaii.edu ). All observations were performed on the ESO New Technology Telescope at La Silla on 2017 June 3, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). The classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). The classification spectra and additional details can be obtained from http://www.pessto.org (via WISeREP) and the IAU Transient Name Server.

(1) Halpha emission consistent with z=0 and blue continuum suggests Galactic origin
(2) Halpha emission consistent with z=0 and flat continuum suggests Galactic origin
(3) Best fit to SN1994ae
(4) Best fit to SN2006N
