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 line at 2.12 μm 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 . Two Herbig-Haro objects are seen in Hα images located close to the positions of maximum H₂ emission.
