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 La Silla-Quest survey (see Baltay et al., PASP, 2013, 125, 683). All observations were performed on the ESO New Technology Telescope at La Silla on the night of 2015-09-22, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). 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
LSQ15bbb | 07:25:16.50 | -69:04:01.1 | 20150918 | LSQ | 17.36 | 0.037 | Ia | around max | (1)
LSQ15bbj | 07:16:14.45 | -69:36:00.2 | 20150918 | LSQ | 19.75 | 0.090 | Ia | +2-5d | (2)
(1) The best match is SN 2007fs at +5d.
(2) Good matches are found at redshifts between z=0.086 and 0.091, at various epochs of +2 to +5 days.
