Measurements performed at wavelength 1.18 cm during the September 11, 1969, partial solar eclipse are described. No significant limb-brightening was detected. However, a high coronal contribution to the emission at this wavelength was observed. Separation between the emission from the center of a unipolar spot of diameter approximately 12 to 1 arc minute and its plage region of diameter approximately 3 to 4 arc minutes was possible. Author
