We report the spectroscopic classification of a La Silla-QUEST (LSQ) supernova (see Baltay et al. 2013, PASP, 125, 683) taken using WFCCD on the 2.5-m du Pont Telescope as part of the Carnegie Supernova Project.
LSQ14bbv was discovered on 19 April 2014 with a V-band magnitude of 18.4 at RA=09:59:33.12 Dec=-56:59:27.84. A spectrum obtained on 5 May 2014 shows the object to be a Type Ia supernova. Cross-correlation with the "Supernova Identification" code (SNID; Blondin and Tonry 2007, ApJ, 666, 1024) reveals the best matches to be the normal Type Ia supernova SN1989B at 8.6days past maximum. SNID also suggests a redshift of 0.057 which corresponds to a photospheric velocity of ~10200 km/s as measured from the minimum of the SiII 6355 Angstrom feature.
