Abstract:

The location of the magnetic anomaly detected with Mechta I coupled with other considerations suggests that the current flowing in the outer Van Allen belt has a distribution with maxima at 25 degrees north and south geomagnetic latitude, and at a geocentric altitude of about 3 earth radii. A current of this type could produce the equatorial and middle-latitude surface variations observed during the main phase of a magnetic storm, variations which as is well known could also be due to a current, such as a ring current, with a maximum in the equatorial plane. In the region above the earths surface the fields of the two types of current distributions are substantially different and hence readily distinguishable. Author
