Abstract
We report discovery of a new young stellar object driving a point-symmetric, near-infrared jet and molecular outflow. The YSO is associated with IRAS 06047-1117 and is embedded in a dense molecular cloud core located southeast of Orion A. The jet is seen in the H2 v=1-0 line at 2.12 $\mu$m and extends over a total length of about ~0.4 pc. The driving source is optically invisible and has near-infrared colors and a spectral energy distribution consistent with a Class I source with an estimated luminosity of 6 $L_{\odot}$. Two Herbig-Haro objects are seen in H$\alpha$ images located close to the positions of maximum H2 emission.


Key words: infrared: stars -- ISM: clouds -- ISM: individual (IRAS 06047 -- 1117) -- ISM: jets and outflows -- stars: formation -- stars: mass-loss
