Short summary
The magnetic equator is the region where the magnetic field is horizontal and therefore strong ionospheric electric currents occur, the so-called equatorial electrojet. The magnetic equator is predicted to be at Macapá state in 2024. Therefore, a new magnetometer station was installed in Macapá in order to track the effects of the equatorial electrojet. We present the setup and data analysis of Macapá station, and we develop a method for temperature correction of the vector magnetometer data.
