We present the first aperture synthesis maps of lambda2.6 mm CO (J = 1-0) emission from an external galaxy, IC 342. The 7'' resolution maps of the nuclear region were made with the Owens Valley Millimeter-Wave Interferometr. They reveal that the CO source is distributed in a bar, 300 pc x > or approx. =1500 pc, with a veloity gradient across the width of the bar. The observations suggest that the molecular gas in the nucleus is moving in response to an oval gravitational potential. The implications of an oval potential on enhanced star formation and other activities are discussed.
