NielsenNoneSN Ia0.055 Inspection of the spectrum indicates this is a Type-Ia supernova at or around maximum light. Comparison to a library of template supernovae spectra using SNID (Blondin and Tonry 2007) reveals good mataches with the normal SN 2006ax and SN 2007F a few days before maximum light. SNID computes a host redshift of z=0.055.
