About the Colloquium
International Colloquium on Equatorial and Low Latitude Ionosphere (ICELLI 2023) is an annual capacity building workshop geared towards understanding of the Sun and its impact on space weather; the dynamics of the equatorial ionosphere, its complexities and 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) which held in Abuja and Ota, Nigeria in 2015 and 2017 respectively. This year’s colloquium would be the 7th edition of this capacity building gathering in Nigeria

Equatorial region, also known as the low latitude region, refers to the region within ± 20° on either side of the geomagnetic equator. The region is characterized with much complexities and high level of dynamics which result in phenomena such as spread F, ionospheric anomaly, equatorial electrojet, equatorial plasma fountain, etc. The impact of such phenomena on telecommunications, navigation, satellite operations, and other space-based technologies has made the region a point of international collaborative focus in scientific research.

The Colloquium is planned to run for a period of 5 days with assorted programs which include 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 modeling of ionospheric scintillation and irregularities, utilization of equatorial orbital plane for satellite technology, presentation of results from different and novel techniques for probing the equatorial ionosphere etc.
This edition shall like the past editions feature a composition of tutorials, seminars, conference and hands on training on every aspect of research and techniques bordering on the dynamics of equatorial and low latitude ionosphere as well as space weather.
This Colloquium shall offer opportunities for presentation of standard contributions (oral and poster), delivery of invited papers by distinguished scientists with the intention of educating young scientists, as well as exhibition of space-dependent technologies and measurement systems relevant to ionospheric studies. The forum shall serve as an effective meeting point for scientists, policy makers, students and designers of space-dependent technologies.
