Dependence of the latitude of the cleft on the interplanetary magnetic field and substorm activity

The latitudinal motion of the cleft (the polar cusp) associated with the southward interplanetary magnetic field (IMF) and substorm activity is examined. The cleft location is identified on the basis of the location of midday auroras and of electron precipitation by the OGO 4 and ISIS 1 satellites. It is found that the IMF and substorm activity control independently the latitude of the cleft and that they can shift the cleft location by 3 or 4 deg under average conditions.

On the cause of northward magnetic field along the negative X axis during magnetospheric substorms

The magnetic fields produced by a three-dimensional current system, consisting of a flow into the morning part of the auroral oval along tail-like field lines, along the auroral oval, and out from the evening part of the oval along tail-like field lines, are computed. It is demonstrated that the major parts of the well-known 'positive bay' in low latitudes on the earth's surface, the positive H variation at the synchronous distance, and the positive Bz variation along the magnetotail during magnetospheric substorms can be caused by the proposed current system.
