Web23 jul. 2024 · During the solar cycle 24, the variability of ionosphere is studied using global positioning system derived TEC at a mid-latitude station, Tehran (35.70N, 51.33E). Based on solar radio flux and... WebIonospheric variability over the low-latitude region of Africa, based on TEC analysis, has been reported before (e.g., Adewale et al. , 2011; Olwendo et al. , 2012; Habarulema et al. , 2013; Andima et al. , 2015 ). From these studies, the diurnal, seasonal, disturbed and quiet-time TEC characteristics over the region have been revealed. WebIn late October 1890, a British force led by Admiral Fremantle assaulted and subdued the East African town of Witu, the mainland capital of the Nabahani rulers of Pate; five years later, the entire region and the adjacent coastal islands came under British administration.
