Abstract

This paper presents the Total Electron Content variability, during the solar cycle 23 maximum under geomagnetic fluctuating activity conditions from 2000 to 2002 at Niamey station (lat. :13°28’N ; long : 2°10’E) in Niger. A comparative study of TEC profiles variation under quiet and fluctuating geomagnetic activity conditions allowed us to analyze the effects of fluctuations in solar wind on equatorial ionosphere. Our investigation argues on that the solar cycle 23 maximum is mostly characterized by a non-effect of fluctuating winds on the ionosphere for equatorial region.

Key words: Seasonal variability, total electron content, fluctuating activity.
