Spectrum is mostly featureless, but displays a weak emerging H-alpha feature at the redshift of the host galaxy (z = 0.039037). A plot of flux*(lambda^2) emphasises the presence of this feature. Combined with its fast rise to peak and peak absolute magnitude of M ~ -18, we classify this as a SN II.
