The highly collimated HH 92 jet and parsec-scale outflow from IRAS 05399-0121.

Abstract (from CDS):

We report the discovery of a 4 pc long bipolar Herbig-Haro outflow driven by a 10 L☉ class I source, IRAS 05399-0121, which is deeply embedded within a submillimeter dust condensation in the LBS 30 cloud core in the Orion B molecular cloud north of NGC 2024. A highly collimated low-excitation jet, HH 92, emerges from an asymmetric infrared reflection nebula and breaks into a cluster of well-resolved Hα-bright bow shocks about 2'.5 northwest of the source. We propose that the well-known objects HH 90 and 91, and some previously uncataloged shocks that lie along the axis of the HH 92 jet, trace a single giant outflow lobe ∼3 pc in length. The object HH 93, which lies about 10' southeast of HH 92, traces the counterflow.
