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 Backyard Observatory Supernova Search (BOSS, http://www.bosssupernova.com/ ). All observations were performed on the ESO New Technology Telescope at La Silla on 2016 04 15, 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) Located at 36E" and 116S" of the nucleus of the host galaxy which is at redshift 0.0074. Best fit with type IIP SN approximately one month post maximum.

(2) Located at 1W" and 13N" of the host galaxy which is at redshift 0.016. Best fit with type IIb SN approximately two weeks post maximum.
