Benetti et al. also obtained a spectrum (as above; range 365- 900 nm; resolution 3.5 nm at wavelength, lambda, > 770 nm) of SN 2003M: "The spectrum, after correction for the redshift of the parent galaxy, reveals a strong resemblance to that of SN 1994I around maximum light for lambda > 500 nm, but it shows weak Fe lines at lambda < 500 nm. This confirms the physical association of the supernova with the elliptical galaxy UGC 7224, even if the supernova is located about 30000 pc from its nucleus. This is possibly the first detection of a core-collapse supernova in an early-type galaxy."
