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 La Silla-Quest survey (see Baltay et al., PASP, 2013, 125, 683) 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 2014-11-24, 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).

 
Name        | RA (J2000)  | Dec (J2000) | Disc. Date | Disc. Source | Disc Mag | z     | Type | Phase | Notes
ASASSN-14jz | 18 44 44.34 | -52 48 05.4 | 20141110 | ASASSN | 15.0 | 0.012 | Ia | +5d | LSQ14gfc | 03 33 07.94 | -33 06 55.9 | 20141115 | LSQ | 21.3 | 0.125 | Ia | -3d | LSQ14gfb | 05 10 05.76 | -36 18 43.5 | 20141115 | LSQ | 21.2 | 0.050 | Ia | -2d | a ASASSN-14ko | 05 25 18.13 | -46 00 20.3 | 20141114 | ASASSN | 17.0 | 0.042 | IIn | - | b

Notes: a) Good match to sub-luminous SN1999by/SN1986G, at or just before max. b) Blue continuum with SN and galaxy emission lines, consistent with SN IIn.
