The time series analysis of solar radio pulsations suggests the existence of a low-dimensional attractor of fractor dimension between 1 and 4. Calculation of the Lyapunov exponent and the Kolmogorov entropy gives some indication of deterministic chaos. Because of the smallness of their data samples, the authors have carried out calculations with a periodic signal and the Lorenz model using the same number of data. Qualitative agreement with the Lorenz model is observed.
