Physics of Auroral Arc Formation
Utilizing data from three satellites the document presents the relationship between the particle energy and angular distributions, the resulting auroral forms, and spatial features such as the inverted V and electrostatic structures. The occurrence o

This is an investigation of stormtime particle transport that leads to formation of the ring current. Our method is to trace the guiding-center motion of representative ions (having selected first adiabatic invariants mu) in response to model substor

Guiding-center simulations of stormtime transport of ring-current and radiation-belt ions having first adiabatic invariants mu is approximately greater than 15 MeV/G (E is approximately greater than 165 keV at L is approximately 3) are surprisingly w

The relationship between the energetic electron environment and electrostatic discharges on the P78-2 (SCATHA) spacecraft has been examined. Internal discharges occur near perigee while surface discharges occur about uniformly over the radial range c

Three energetic solar proton events occurred in the August to October 1989 time period. The energetic (1-10 MeV proton fluence from these events was among the highest fluence levels observed during the space age. The solar proton events were of suffi

Long-term (1979–88) observations of relativistic electrons in the earth's outer magnetosphere show a strong solar cycle dependence with a prominent intensity maximum during the approach to solar minimum (1983–85). This population therefore corres

We use a dynamical guiding-center model to investigate the stormtime transport of ring current and radiation-belt ions. We trace the motion of representative ions' guiding centers in response to model substorm-associated impulses in the convection el
