Abstract Supernova 1984A was a remarkable Type Ia event which exhibited extremely high-velocity material in its spectrum. The optical light curve of this supernova is marked by a rapid decline, which further distinguishes it from common Type Ia events, but the optical spectra are, apart from the persistent, unusually larger Doppler shifts, practically identical to previously well-observed Type Ia supernovae such as SN 1981B. In contrast to the extreme optical peculiarity of this supernova, the IR light curves are almost normal. Only one other Type I supernova is known to have a light curve which is as fast as SN 1984A-SN 1885 in M31, S Andromedae. S Andromedae has been classified as a peculiar Type I on account of its unusual light curve. But now that such a fast light curve is no longer unprecedented, we can classify S Andromedae as a Type Ia supernova.
