Two highly polarized lobes near tge Galactic Center.

Two polarized lobes near the galactic center have been detected at 10 GHz using a multichannel polarimeter on the 45-m telescope of the Nobeyama Radio Observatory. These lobes are located on both the ends of the radio arc, 10 arcmin from the galactic center, and extend perpendicular to the galactic plane. The northern lobe is polarized up to 60 percent, the transverse magnetic field lies along the major axis of this feature, and a component is directed toward the observer. On the other hand, the southern lobe is not as highly polarized, and the magnetic field orientation is complicated. At the radio arc the Faraday rotation is very large and the sign of rotation measure is negative, while in the southern extended tail the rotation is positive. Properties of the lobes and the magnetic field configurations are briefly discussed.
