Longitudinal difference in the Sq profiles in the South American region

The average daily variation profiles of the H component at Huancayo on the west coast and Eusébio, Fortaleza, on the east coast in the dip equator region and La Quiaca near the west coast and Vassouras near the east coast in the southern low latitude region of the South American continent indicate that the profiles are broader for the east coast. Thus, distortions in the overhead current systems while passing from one coast to the other are indicated.
