80 MHz aperture synthesis observations of the Galactic center region made with the Clark lake TPT array are presented. The sources G 1.05 - 0.1, G 0.9 + 0.1, and G 0.16 - 0.15 were detected in emission. The detection of G 0.16 - 0.15, coincident with the southeastern part of the continuum arc feature, is evidence of nonthermal emission in this region of the arc. Several H II regions also appear in absorption against the nonthermal Galactic background. In addition a strong unidentified extended nonthermal source located approximately 34 arcmin from the Galactic center was detected. Although no direct evidence for the distance to this object is currently available, the properties of this source are very similar to those exhibited by radio lobes observed in the nuclei of Seyfert galaxies as reported by Wilson in 1981 and later papers. However, the possibility that this object is a Galactic SNR with an unusually step spectrum cannot be ruled out.
