The seasonal variation of the electron density profile in equatorial anomaly region is investigated using Global Positioning System (GPS) ionospheric tomography method from a dense network of Malaysian Real-Time Kinematic Network (MyRTKnet). In this study, the monthly variation of the electron density is reconstructed to study the development of the equatorial anomaly crest over the study area. It is found that the equatorial anomaly crest appears during the noon and last for a few hours before disappeared. The result also shows that the anomaly crest show strong appearance during both equinoxes, where March to May shows stronger crest compared to October to November month-to-month variations.
