High-Altitude Observations of an Intense Inverted-V Event.
Abstract
Inverted-V events which generally occur in the pre-midnight sector over the auroral zone are frequently associated with reversals in the convection electric field. Such a reversal is observed by the University of Iowa quadrispherical LEPEDEA on board ISEE-1 at an altitude of 13 RE on 1 May 1978. The bulk of the plasma shows a large shear over a five-minute interval. The associated change in the convection electric field is 5.1 mV m-1. Large values of the field-aligned current are simultaneously detected. The potential structure appears to extend to the satellite location. Using a theoretical model we have calculated the field-aligned current due to the electric field discontinuity. The magnitude of the parallel potential drop and width of the inverted-V region agree well with observation. (Author)
