Abstract : We discuss the comprehensive analysis of spectrophotometric time-series observations of the Type Ia supernova SNF20080514-002. The data consist of 20 SuperNova Integral Field Spectrograph (SNIFS) spectra sampled over 50 days, commencing at 10 days before peak brightness. The analysis is part of a systematic effort to map out the time-dependent manifestation of ion species in Type Ia supernova spectra in detail. In general, the SN is relatively normal, but it possesses some noteworthy characteristics we explore in detail. C II footprints are detected in the spectra leading up to maximum light, suggesting that unburned material may be mixed with intermediate mass burning products. Though the light-curve qualifies as a moderately fast-decliner (s=0.87), its UV-optical colors are unusually blue. We attempt to place these findings into the context of supernova explosion models, and comment on whether the occurrence of carbon in lower-luminosity Type Ia supernovae favors any particular model or not.
