PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see Smartt et al., arXiv:1411.0299 http://www.pessto.org ) reports the following supernova classifications. Targets were supplied by the La Silla-Quest survey (see Baltay et al., PASP, 2013, 125, 683) and OGLE-IV Real-time Transient Search (Wyrzykowski et al., 2014 arxiv:1409.1095;http://ogle.astrouw.edu.pl/). All observations were performed on the ESO New Technology Telescope at La Silla on 2014-11-13, 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. Extended, but faint H-alpha from the host at z=0.024 +/- 0.002. Best SNID matches are with 1991T-like templates at -7d, at z = 0.026 +/- 0.007. Announced in ATel #6694 (Nicholls et al.). 2. Peculiar type II. Already 17days old (not visible on LSQ images on 20141026). Blue spectrum, weak H-alpha with no P-Cygni absorption trough. Galaxy lines at z=0.038. Peaked at M ~= 17.3 Spectrum match for SN2004et, but around +6d after explosion. 3. Likely a normal II-P at 20-30 days after explosion. Two OGLE points show constant i-band brightness over 10 days.
