Abstract : Fluctuations of solar radio emission at 4 cm were investigated using the radio interferometer with the small base. A construction of autocorrelation functions permits the detection of fluctuations with the periods of 10 to 15 min and more, and amplitude up to 0.5 to 0.7 percent of the undisturbed sun. It is shown that the periodic fluctuations of the flux are connected with separate local sources. These fluctuations are assumed to be due to proper oscillations of a coronal condensation - a condensed plasma, restricted by the magnetic field of the force lines rope in a sunspot group. (Author)
