VLA observations of an HH-like object, known as the Orion 'streamers' in the L1641 cloud, have been carried out at wavelengths of 2, 6, and 20 cm. This object is located several arcminutes to the north of HH 34 and exhibits a unique morphology which consists of a long and narrow structure with approximate dimensions of 10 x 300 arcsec in optical photographs. A significant linearly polarized emission at 6 cm arising from near the core of the streamers has been detected, indicating uniform magnetic field geometry. This result suggests that the source responsible for producing the nebulosity is a nonthermal-emitting radio source. Because of the presence of a number of newly born low-mass stars in the vicinity of the streamers and because of the detection of a faint highly reddened 2-micron source coincident with the polarized radio emission, it is believed that the source at the core of the streamers is a low-luminosity young star responsible for both the synchrotron emission and the shock nebulosity.
