Vertical Electric Currents in Active Regions: Calculation Methods and Relation to the Flare Index
Fursyak, Yu. A.
In the scope of the performed work, two problems are solved. The first is the analysis of two existing methods for calculating vertical electric currents, differential and integral. The integral method has some advantages compared to the differential method. Among them, one can mention there is no need to differentiate the magnetic field and a goo…
The Effect of the Betatron Mechanism on the Dynamics of Superthermal Electron Fluxes within Dipolizations in the Magnetotail
Daly, P. W.; Malykhin, A. Yu.; Grigorenko, E. E. +1 more
The dynamics of high-energy electron fluxes (with energies over 40 keV) is analyzed in 13 events of magnetic field dipolization observed by the Cluster satellites in the near-tail of the Earth magnetosphere. In all of the events, the observed energetic electron fluxes are enhanced simultaneously with initial dipolization. Good correlation (correla…
