Abstract:
A study of the geomagnetic solar flare effect (SFE) of July 6, 1968, observed at five Indian magnetic observatories, lying in the longitude range 72-80 E, revealed that this SFE is characterized by a decrease in the H-component at electrojet stations and an increase in the H-component at stations outside the electrojet. Examination of relevant ionogram and magnetogram data recorded at Kodaikanal, a station under the electrojet, indicated the existence of a counter-electrojet just prior to and after the occurrence of SFE.
