Total Electron Content (TEC) estimated from GNSS data is a good indicator of the behavior of the ionosphere. This study searches for possible longitudinal differences between the behavior of TEC and its day-to-day variations between two ranges of longitudes in Equatorial Ionosphere Anomaly (EIA)-affected low-latitude African stations. The study considers TEC daily values at 05:00 and 13:00 LT for the high solar activity year 2014. In addition, the day-to-day variability of TEC at those given hours was calculated by analyzing the difference between two consecutive daily values of TEC (DIFFTEC) at the same hours. The correlation coefficients (R) and corresponding coefficient of determination (R²) were used to identify the possible correlation between data from two locations, each in the eastern and western sectors of the low-latitude African region. Also possible correlations between data from different longitudinal sectors were studied. Values of the correlation coefficient indicate that at 13:00 LT there is a reasonably high correlation between TEC in the same longitude sector but also between stations in the two longitude sectors considered. The correlation is much reduced in both cases at 05:00 LT. The day-to-day variability, as indicated by DIFFTEC, shows larger variability in the Eastern Sector than in the Western sector. At 05:00 LT, a seasonal variation with higher variability in DIFFTEC standard deviation in the equinoctial months appears in both sectors, being larger in the Eastern sector. Locations in both sectors have shown higher variability of DIFFTEC standard deviation at 13:00 LT than at 05:00 LT.
