Abstract:

Progress has been made in four areas 1 Mapping the different regions of the magnetosphere into the ionosphere under varying solar wind conditions. This research is relevant to future USAF operational systems needs in that the environment experienced by a spacecraft differs greatly depending on the region being transited. 2 Understanding the convection surge mechanism in the magnetotail. 3 Determining the plasma source region for dayside auroral emissions through coordinated satellite imagery and particle data. 4 Creating a new interpretation of dayside auroral transients, involving directly driven ionospheric response to magnetosheath changes.
