PESSTO, the 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 OGLE-IV Real-time Transient Search (Wyrzykowski et al., 2014 arxiv:1409.1095; http://ogle.astrouw.edu.pl/ ), from the ESA Gaia Photometric Science Alerts Team and DPAC (http://gsaweb.ast.cam.ac.uk/alerts), by Pan-STARRS Survey for Transients (see Huber et al., ATel #7153), and from the All Sky Automated Survey for SuperNovae ASAS-SN (see Shappee et al. 2014, ApJ, 788, 48 and http://www.astronomy.ohio-state.edu/~assassin/index.shtml ). All observations were performed on the ESO New Technology Telescope at La Silla on 2016 September 28th, using EFOSC2 and Grism 13 (3985-9315A, 18A 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) Appears to be a galaxy at z = 0.039
(2) Noisy spectrum but SNID matches various SNe Ia a couple of weeks past maximum light
(3) Type Ia SN similar to SN 1992A according to SNID
(4) SNID best match is Type Ia SN 2007fs
(5) SNID best fit is to Type Ic SN 1983V several days after maximum but also finds good fits to other SNe Ibc up to +2 weeks
(6) SNID matches the normal Type Ia SN 1999ej approximately two weeks after maximum light
(7) The best SNID fit is to Type Ia SN 2005cf
