Deep BJ and H-alpha images on the dwarf elliptical galaxy NGC 3077, which is undergoing enhanced star formation presumably as a result of its acquisition of gaseous material in an encounter with its neighbor, the giant spiral M81, are presented and discussed. A current star formation rate of about 0.1 solar mass/yr is estimated over a region about 700 pc across centered on the nucleus. The derived efficiency of star formation is higher than that found for isolated spirals, although there are considerable uncertainties in the assumptions that go into this calculation. The characteristics of star formation and the interstellar medium in NGC 3077 is compared with that in the other dwarf member of the M81, system, M82. It is argued that, although the total mass of gas in the two galaxies is roughly similar, M82 is much more effective a turning it into molecules, the fuel for star formation.
