PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see Valenti et al., ATel #4037; http://www.pessto.org ), reports the following supernova classifications. Targets were supplied by the OGLE-IV Transient Search (see Wyrzykowski et al., ATEL #4495) and TOCP webpages. All observations were performed on the ESO New Technology Telescope at La Silla on 2013 August 29 (UT), using EFOSC2 and Grism 13 (3985-9315A, 18/27A resolution). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and GELATO (Harutyunyan et al., 2008, A&A, 488, 383). Classification spectra can be obtained from http://www.pessto.org via WISeREP (Yaron & Gal-Yam, 2012, PASP, 124, 668).

(1) Reddened SN Ia about one week before the maximum light.

(2) Young SN II. Match with several SNe II-P around and before the maximum light.
