Abstract
The paper describes the daily variations in the Sq and sfe induced ionospheric current at the equatorial stations of Addis-Ababa (Inclination: 1.0°; Declination: 1.5°) and M’Bour (Inclination: 9.0°; Declination: −9.3°). At Addis-Ababa, the diurnal SqH loop as well as sfe H currents aligned fairly well with the direction of declination. At M’Bour, the SqH as well as the sfe H vector were along the direction of about 30°W. Thus, in the region of an abnormally large declination at equatorial stations, the daily Sq current does not follow a direction normal to the declination.
