External Sq currents in the West African region

The external Sq currents for quiet days in 1993 were studied for the West African re- gion using the magnetic data obtained in the course of the French participation in the International Equatorial Electrojet Year (IEEY). Spherical Harmonic Analysis technique was used to separate the internal and...
