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 classifications. Targets were supplied by Pan-STARRS Survey for Transients (see Huber et al., ATel #7153). We acknowledge ESA Gaia, DPAC and the Photometric Science Alerts Team (http://gsaweb.ast.cam.ac.uk/alerts). All observations were performed on the ESO New Technology Telescope at La Silla on 2016- 07-31, 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) Best fit with normal type Ia SNe a few days before the maximum light. The redshift is for the host galaxy ESO 466-G032.
(2) Best fit with normal type Ia SNe e.g. SN 2005cf at the maximum light.
(3) Possible CV. Blue continuum and possible weak absorption at 4861A.
(4) CV showing a blue continuum, Halpha in emission and Hbeta and higher Balmer series in absorption.
(5) The object not visible in imaging.
