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). All observations were performed on the ESO New Technology Telescope at La Silla on 2013 October 23, 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 can be obtained from http://www.pessto.org (via WISeREP).

(1) Good match with several normal type Ia SNe 2-4 days after their maximum light.

(2) Supernova with some extinction. Good match with several normal type Ia SNe around maximum light.
