PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see Valenti et al., ATel #4037; http://www.pessto.org ), reports the following supernova classifications. One target was supplied by the Catalina Real-time Transient Survey (http://crts.caltech.edu/). The observations were performed on the ESO New Technology Telescope at La Silla in the night starting on 2014 May 04 UT, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were made 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) Blue continuum with absorption features between 5000 A and 6000 A comparable with Ca II and the O II triplet in absorption at z=0.35 +/-0.02 and usually seen in SLSNe Ic
(2) Best match to SN1992H at +40d since explosion
(3) Best match to several Type Ia before max (-3d < phase < -2d)
(4) Galactic red dwarf with two broad emission lines at 6560 A and 7040 A of FWHM 160 A and 114 A, respectively. These emissions are comparable with Halpha and TiO
