SN Ia

adH0cc

The spectrum is similar to those of normal Type Ia supernovae about a week before B-band maximum. GELATO (Harutyunyan et al., 2008) identifies SN 2003kf around day -8 as the best match for this supernova. The redshift was determined based on the wavelengths of narrow H-alpha and [NII] emission lines of the host galaxy. Based on the redshift, the measured Si II line velocity is approximately 12000 km/s.
