Sensitive observations of carbon monoxide toward the Kleinmann-Low (KL) infrared nebula in Orion have revealed the presence of low-level emission extending over a radial velocity range of at least 150 km s/sup -1/. The high-velocity emission appears to be localized to a region approximately-less-than1' in diameter centered on KL. The high-velocity gas is probably associated with pre- rather than post-mainsequence object(s). However, the intensity of line radiation at these high velocities is not easily explained with simple models of mass-outflow, gravitational collapse or rotation. (AIP)
