PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see Smartt et al. 2015, A&A, 579, 40 http://www.pessto.org ), reports the following supernova classification. Targets were taken from the CBAT Transient Objects Confirmation Page (http://www.cbat.eps.harvard.edu/unconf/tocp.html). All observations were performed on the ESO New Technology Telescope at La Silla on 2015 Oct. 06, 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) The spectrum is blue, with broad Halpha, Hbeta and NaD/ HeI 5876, consistent with a Type II SN a few days after explosion.
