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 La Silla Quest Variability Survey (see Baltay et al. 2013, PASP, 125, 683), ESA Gaia, DPAC and the Photometric Science Alerts Team (http://gsaweb.ast.cam.ac.uk/alertsc), and from CRTS SNHunt (Drake et al. 2009, 696, 870 ; http://crts.caltech.edu/ ). All observations were performed on the ESO New Technology Telescope at La Silla on 2016 February 25th, 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) and the Transient Name Server.

a. A good match is found with SN 2006aj around maximum light.
b. A good match is found with OGLE-2013-SN-079. Also note that the object has a remote location compared to its host.
c. Probably a CV.
d. Discovered originally as LSQ16te.
e. Discovered originally as LSQ16sf.
f. Blue continuum, with a narrow resolved Halpha emission line and a broad Hbeta P-Cygni line. Note that this is an updated classification. The object was originally classified in ATEL #8734 as a Type IIn.
g. Object with a significant extinction: E(B-V) ~ 0.7
h. Discovered originally as SNHunt309.
