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 the La Silla-Quest survey (see Baltay et al., PASP, 2013, 125, 683). All observations were performed on the ESO New Technology Telescope at La Silla on 2016 04 05, 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 and additional details can be obtained from http://www.pessto.org (via WISeREP) and the IAU Transient Name Server.

(1) Discovered by LSQ with ID LSQ16ajh. Best fit with several type IIb around maximum light at z=0.04.
(2) Discovered by LSQ with ID LSQ16aki. There is a broad emission feature around 5500 Ang, which could correspond to the 2800 Ang Mg II feature of a z=0.96 QSO. This source coincides with LQAC_185-026_001 in the Large Quasar Astrometric Catalogue 3 (LQAC-3; Souchay+, 2015) and is detected in the Radio.
