Solar flare effects in geomagnetic field at Indian stations-Part III: Alibag, outside equatorial electrojet

摘要

The paper describes the solar flare effects(SFEs)in horizontal(H), eastward(Y)and vertical(Z)fields at Alibag, a station outside the equatorial electrojet current region. The amplitude of SFE(H)is a broad maximum Around noon, while SFE(Y)is positive in the forenoon and minimum in the afternoon hours. The SFE(Z)field Seems to be negative at any time of the day. These features are consistent with the effects expected of a normal S_q current over the station.
