Dayside Magnetosphere and Ionosphere:
When the Interplanetary Fast Forward Shock Arrives

ABSTRACT

Interplanetary fast forward shocks have significant effects on the dayside magnetosphere and ionosphere. The phenomena include shock generated field-aligned currents, increased ionospheric convection as well as enhanced auroral brightening and propagation etc. To understand the mechanisms, data from Polar, FAST, DMSP, SuperDARN and the groundbased magnetometers are analyzed. It is suggested that an identification of shock-aurora forms could provide an answer to all speculations. Therefore, an idea of conducting the auroral observation using high-altitude and long-duration balloons is being evolved.
