PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see Valenti et al., ATel #4037; http://www.pessto.org ),
reports the following supernova classifications. Targets were supplied by the La Silla-Quest survey (see Hadjiyska et al.,
ATel #3812). All observations were performed on the ESO New Technology Telescope at La Silla on 2012 October 14 and 16,
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
LSQ12fjm | 04:36:10.93 | -05:04:53.4 | 20121010 | LSQ | 18.26 | - | not a SN | - | See note (1)
LSQ12fiq | 04:41:40.78 | -09:53:34.4 | 20121010 | LSQ | 19.69 | 0.15 | Ia | around maximum |
(1) LSQ12fjm has a noisy spectrum that resembles either a late-type galaxy or late-type star. It is most likely a stellar transient
as the galaxy fit produces z=0, and the faint host galaxy source visible in SDSS DR8 is too faint to contribute to
the observed transient flux.
