PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see Valenti et al., ATel #4037; http://www.pessto.org ), reports the following supernova classifications. The targets were supplied by the OGLE-IV Transient Search (see Wyrzykowski et al. ATEL #4495) and amateur astronomers (http://www.cbat.eps.harvard.edu/unconf/tocp.html). All observations were performed on the ESO New Technology Telescope at La Silla in the night starting on 2013 January 21 UT, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). The classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and both objects are well fit by many young Type IIP supernovae. The classification spectra can be obtained from http://www.pessto.org (via WISeREP).
