Abstract

New high-resolution observations at 843 MHz, and 5 and 8.4 GHz of the galactic supernova remnant G291.0 - 0.1 are described. The emission from the remnant is dominated by an elongated centrally bright component surrounded by weaker extended emission and subsidiary peaks. Polarization of the main component implies an orderly magnetic field aligned along its major axis. The radio emission has a relatively flat spectrum (S inversely proportional to v exp -0.29), in common with other filled-center remnants. The peak of the X-ray emission lies on the major axis of the elongated radio component.
