Title: Residual Disturbance Field (JD) in the Indian Equatorial Region
Authors: Bhargava, B. N.

Abstract: The residual disturbance field has been derived at one low latitude station and three stations in the equatorial electro jet belt in the same longitude zone for typically quiet to moderately disturbed conditions by successive elimination of non-cyclic variation, Sq. L and Dst. The main features of the field, so computed from samples of data from high, relatively low and declining phases of solar activity cycle have been discussed The component of the residual field at Trivandrum, close to the dip equator, which can be associated with the modulation of the electro jet by disturbance, has also been computed and found to consist primarily of a southward directed field around 10-11 hrs LT and, in two of the three samples, this is followed by a northward field in the afternoon hours. The relative magnitudes of these fields at the stations in the electrojet belt suggest an equatorial enhancement. A striking feature of the residual field, a progressive increase of its mean level with magnetic activity, is discussed in relation to return currents of the eastward and westward polar electrojets.
