PESSTO, the Public ESO Spectroscopic Survey for Transient The Objects (see Valenti et al., ATel #4037; http://www.pessto.org ), reports the following supernova classifications. Targets were supplied by Pan-STARRS Survey for Transients (see Huber et al., ATel #7153). All observations were performed on the ESO New Technology Telescope at La Silla on 2015 December 02, 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) Low S/N spectrum, showing narrow and unresolved hydrogen emission lines and a fairly flat continuum (r - i = 0.3 ± 0.1). No evidence of any broad SN features. M_r = -17.4 (including A_r = 0.4 Galactic foreground extinction).
