We have used the Multiple Mirror Telescope as a phase coherent array to map the CO J = 3-2 emission from the central 1' region of the Orion molecular cloud. The angular resolution was 26'' and the absolute pointing accuracy was better than 5''. The peak radiation temperature of the high-velocity gas is approximately 75 K, and the characteristic size of the emission region is 30''--40''. The centroid of the high-velocity emission is located roughly 10'' northeast of IRc2. The peaks in the emission strength of the redshifted and blueshifted high-velocity CO are offset with the redshifted emission peaking east and the blueshifted emission peaking north of IRc2. The axis of the high-velocity CO emission is aligned with the two maxima of the 2 ..mu..m H/sub 2/ emission suggesting that the CO is participating in the same bipolar outflow.
