Greyscale of the 2.12um S(1) line emission from molecular hydrogen with contours of red- and blue-shifted CO J=2-1 emission overlaid. Two of the lobes are positionally coincident with jets of vibrationally excited molecular hydrogen emission; these outflow lobes and the hydrogen emission clearly comprise a small (~0.2 pc) bipolar outflow. The remaining CO outflow lobes are symmetrically placed about the IRAS source and comprise a larger scale (~0.5 pc) bipolar outflow structure. While a single source might be capable of producing both outflows, the large difference in the position angles of the two outflow structures (52 degrees) and their clean separation, coupled with the extreme youth of this source (based on its invisibility in the near-infrared) place unreasonable constraints on a precessing source model. A more plausible hypothesis is that two equally young sources are currently forming in reasonably close proximity from a single dense core, and that each source is powering one of the observed outflow structures.
