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/ ), and by MASTER (see http://observ.pereplet.ru/ ; Lipunov et al. 2004, AN, 325, 580). All observations were performed on the ESO New Technology Telescope at La Silla on 2016 October 21, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). The classification was done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). Classification spectrum and additional details can be obtained from http://www.pessto.org (via WISeREP) and the IAU Transient Name Server.

(1) Spectroscopically similar to
SN 1987A several days before maximum, but OGLE light curve shows that the SN is close to maximum or just after maximum.
