Prediction of ionospheric scintillation using neural network over East African region during ascending phase of sunspot cycle 24

VHF and GPS-SCINDA receivers located both at Nairobi (36.8°E, 1.3°S) in Kenya and at Kampala (32.57°E, 0.335°N) in Uganda were used to investigate ionospheric scintillation and forecast scintillations of a few hundred meter-scale irregularities associated with equatorial ionospheric irregularities for the period 2011 and 2012. VHF scintillations was characterized by long duration of activity and slow fading that lasted till early morning hours (05:00 LT). Furthermore, different percentage occurrence of scintillations in some months were observed, but found that weak scintillation (0.2
