Observations of the J = 2-1 and J = 1-0 transitions of /sup 12/CO and /sup 13/CO reveal the presence of high velocity molecular gas associated with a low luminosity infrared source in the vicinity of the Herbig-Haro objects HH 7--11. The blueshifted and redshifted wings show peak intensities spatially separated by 1X5 (0.2 pc), suggesting an energetic bipolar outflow of gas from a young low mass star. The mass loss rate implied by these observations is 8 x 10/sup -6/ M/sub sun/ yr/sup -1/.
