Abstract
Azimuthal variation of solar wind velocity in the range 300-450 km s-1 has been found to exist along the current sheet during 1972-1977. The possibility of using the A(p) index (when the earth goes through an I MF sector boundary crossing) to study the azimuthal structure of solar wind has been analysed. The longitudinal variation of the A(p) index in terms of Carrington longitude is found to be similar to that of the solar wind velocity variation.
