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 ATLAS survey, see Tonry et al. (2011 PASP, 123, 58) and Tonry et al. (ATEL #8680), the 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 2016 Nov 03, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024), SuperFit (Howell et al., 2005, ApJ, 634, 1190) 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) Low S/N blue spectrum. Object faded 0.6mag in 4 days after first discovery. A faint source is detected in the PS1 3Pi sky stack in i and z, which looks point like. This is likely a galactic variable, and CV candidate (b=-17 degrees).
(2) Otherwise known as ATLAS16dpd. Best match to SN1999aa.
(3) Identified by citizen scientists in the Supernova Hunters project; we acknowledge the contribution of Zooniverse Citizen Scientists 'marisa_gomez', 'nilium' and 'chrostek'.
