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 La Silla-Quest survey (see Hadjiyska et al.,
ATel #3812) and OGLE-IV (ATel #4495; Wyrzykowski et al. 2012) . All observations were performed on the ESO New Technology Telescope at La Silla on 2013 November 22, 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) OGLE-2013-SN-118 Best spectral matches are normal Ia a few days before peak, or 91T-like at or just after peak.
Large offset from likely host.
