PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see Smartt et al., arXiv:1411.0299 http://www.pessto.org ) reports the following supernova classifications. Targets were supplied by the Pan-STARRS Survey for Transients (see Huber et al., ATel #7153) and the All Sky Automated Survey for SuperNovae ASAS-SN (http://www.astronomy.ohio-state.edu/~assassin/index.shtml). All observations were performed on the ESO New Technology Telescope at La Silla on 2015-03-10, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and superfit (Howell et al. 2005, Ap.J. 634, 1190). Classification spectra can be obtained from http://www.pessto.org (via WISeREP).

a) Spectroscopically similar to PTF12dam 
b) Blue continuum with weak absorption features. Redshift secure from narrow H-alpha and H-beta 
detections which are probably galactic. Possibly a young IIn, and reasonable match to 1998S around maximum. 
c) Possible match to a type IIb @ +10 days
