Abstract : Summaries are given of results obtained from total electron content measurements, scintillation observations and spaced aerial irregularity studies in East Africa. The development and movement of the equatorial anomaly in total electron content throughout the day is examined for different seasons and the effects found to be most pronounced in the equinoxes. Some control by magnetic acitivity is indicated. A number of problems in the data reduction are discussed. Variations in the extent of the F-region equatorial irregularity belt with season and local time have been found. Irregularities have been detected (by dispersion analysis) at heights from 85-800 km, the average size (20-400 m) being almost constant at all altitudes. The maximum occurrence is found at or near hmF2 and at Es heights. The movement of irregularity patches is predominantly towards the east before 0600 L.M.T., and to the west after this time. Considerable polarization scintillation is found at 20 MHz. (Author)
