Abstract : The report summarizes previous work on ionospheric scintillation done at Legon, Accra, Ghana. It gives smoothed curves showing the seasonal variation of scintillation for the parts of 4 successive years (1967-70) for which records were obtained. The report also shows that nights of much reduced scintillation are also nights of unusually high values of Faraday rotation angle. It is shown that there is a statistically significant reduction of scintillation on nights of magnetic disturbance characterized by a high value of the K(p) index. It compares scintillation data from Legon, Ghana and Huancayo Peru, over a six month period, and briefly reviews present knowledge of the convective motion of field lines in the magnetosphere, and shows that equatorial scintillation is closely associated with that motion.
