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 by the Katzman Automatic Imaging Telescope (see ATel #5783). All observations were performed
on the ESO New Technology Telescope at La Silla on 2014 January 23 UT, 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).
