We discuss the relatively broad spectrum of fluctuations in flux which is observed at cm-wavelengths when tracking a small area on the Sun's disk. The distribution of power P over the frequencies ω of fluctuations can be approximated by a power-law where α ≃ 2; often a continuous “curvature” is superimposed and a “turnover” frequency is indicated at about ω/2π ≃ 10−3 Hz. Considering the phases of different Fourier components of the time series measured, a significant linear correlation is found between phases of neighbouring frequencies.
