The aim here is to examine ionospheric anomalies through variations in Total Electronic Content (TEC) recorded at the Koudougou GPS station over solar cycle 24 during periods of corotation activity. Through the diurnal variations by solar phase, we observed a TEC peak at 14:00 TL. The TEC data analysed revealed winter, annual and semi-annual anomalies. However, the equinoctial anomaly was insignificant during corotation activity at the Koudougou station during solar cycle 24. %K Geomagnetic Activity %K Total Electronic Content %K Ionospheric Anomalies %K Equinoctial %K Corotation Activity %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=139952
