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 April 29 UT, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were made using superfit (Howell et al. 2005, ApJ 634, 1190) and GELATO (Harutyunyan et al., 2008, A&A, 488, 383). Classification spectra can be obtained from http://www.pessto.org (via WISeREP).

(1) Flat spectrum, no broad features.
(2) Good spectral matches are found to IIb SNe such as SN 2011fu (Kumar et al. 2013) at ~10-20 d post explosion.
