The most interesting result from observations is the recognition of a system of narrow filamentary structures, which make up the continuum arc, having typical widths of 20 arc seconds (~1 pc). These radio filaments are perpendicular to the galactic plane , parallel to each other, regular, unbroken and homogeneous in their appearance. The presence of a halo of 8 armin diameter (24 pcs) surrounding the Sgr A East shell can also be seen. This halo consists of a number of large scale protrusions directed pe rpendicular to the galactic plane.
