Register to Attend the ICELLI 2023


The International Colloquium on Equatorial and Low Latitude Ionosphere (ICELLI 2023) is an annual capacity-building workshop geared towards an understanding of the Sun and its impact on space weather, the dynamics of the equatorial ionosphere, its complexities and the high level of dynamics which results in phenomena such as spread F, ionospheric anomaly, equatorial electrojet, equatorial plasma fountain, etc.; and how space weather impact on telecommunications, navigation, satellite operations, and other space-based technologies.

The Colloquium metamorphosed from a summer school-like programme tagged International School on Equatorial and Low Latitude Ionosphere (ISELLI), held in Abuja and Ota, Nigeria, in 2015 and 2017, respectively. This year’s colloquium would be Nigeria’s 7th edition of this capacity-building gathering.

The Colloquium is planned to run for five days with various programmes, including discussions of the rather wide range of phenomena, such as equatorial ionosphere, equatorial electrojet, equatorial ionospheric anomaly, geomagnetic disturbances, geomagnetically induced currents, solar-terrestrial relations, stratospheric warming, space weather, theory and modelling of ionospheric scintillation and irregularities, utilisation of equatorial orbital plane for satellite technology, presentation of results from different and novel techniques for probing the equatorial ionosphere etc.
