Spectra from five nights near maximum light are presented for SN 1989B in NGC 3627. SN 1989B appears to be a typical Type Ia supernova with an envelope expansion velocity of about 10,600 km/s near maximum light. The presence of diffuse interstellar bands and Na I absorption attributable to the interstellar medium (ISM) of NGC 3627 indicates significant obscuration of the supernova. If relations between the strengths of these features and E(B - V) derived for the Galaxy can be applied to the ISM of NGC 3627, the indicated E(B - V) is about 0.8 for SN 1989B. 11 refs.
