A 2.12 μm S(1) line + continuum image containing two separate systems of H2 knots. The circle identifying HOD07 11 at 6h7m46.9s, −6°20﹩\arcmin﹩6﹩\arcsec﹩ marks the putative position of the central source of a jet extending to the north‐northeast (﹩\mathrm{P.A.}\,\approx 23^{\circ }﹩) and ending in a well‐defined bow shock located at 6h7m48.6s, −6°19﹩\arcmin﹩3﹩\arcsec﹩. Several fainter knots of S(1) emission lie between the center and the bow shock, completing the morphology of a typical jet. HOD07 12 at 6h7m49.8s, −6°20﹩\arcmin﹩43﹩\arcsec﹩ has the morphology of a faint bipolar nebula. Two other knots of S(1) emission lie to the southeast at 6h7m51.6s, −6°20﹩\arcmin﹩58﹩\arcsec﹩ and at 6h7m54.9s, −6°21﹩\arcmin﹩57﹩\arcsec﹩. While there are a number of faint features to the northeast of the bipolar nebula, no clear association with this jet source can be established.
