Description:

Based on 5 years (2001 –2005) of magnetic ﬁeld measurements made by the CHAMP satellite, latitudinal pro ﬁles of the equatorial electrojet (EEJ) have been derived. This study provides a comprehensive characterization of the reverse current EEJ sidebands. These westward currents peak at ±5° quasi-dipole latitude with typical amplitudes of 35% of the main EEJ. The diurnal amplitude variation is quite comparable with that of the EEJ. Similarly to the EEJ, the intensity is increasing with solar EUV ﬂux, but with a steeper slope, indicating that not only the conductivity plays a role. For the longitude distribution weﬁnd, in general, larger amplitudes in the Western than in the Eastern Hemisphere. It is presently a
