We have observed /sup 12/CO and /sup 13/CO emission from Orion A, using the Owens Valley Millimeter Interferometer. We have detected CO emission from a source at 5 km s/sup -1/ V/sub LSR/ in the vicinity of the NH/sub 3/ ''hot core'' source. We estimate a mass of 5 M/sub sun/ for this source, for which we find a size of approx.12''. The E-W size of the plateau source is measured to be approx.17'', implying a high density (approx.5 x 10/sup 6/ cm/sup -3/) for the gas in the outflow.
