Source of the high-velocity molecular flow in Orion

We present 6'' resolution aperture synthesis maps of the 86.8 GHz SiO (v = 0, J = 2-1) emission from Orion-KL. The maps show that the ''high-velocity'' molecular flow in this region is bipolar and originates within a few arc seconds of the infrared source IRc2. The blueshifted SiO line wing arises from a well-defined lobe which extends W from IRc2, while the redshifted line wing is strongest to the E of IRc2. The axis defined by the high-velocity SiO emission is not well aligned with the lobe of vibrationally excited H/sub 2/ emission to the NW of IRc2.
