Geomagnetic storms from solar eruptive events
Paper: Geomagnetic storms
have been studied intensely for over 30 years. To understand the
effects of solar eruptive events on the magnetosphere we have almost exclusively
relied upon in situ measurements in the magnetosphere and solar wind.
The application of remote sensing techniques has a high potential of obtaining
unprecedented data on the dynamics of geomagnetic storm and substorm processes
and in particular determining the relationship between a variety of global
The Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) mission
will have an impressive array of remote sensing instruments which will
image a number of important phenomena such as the auroral zone, the geocorona,
the ring current, the plasmasphere, auroral ion fountain, and the magnetopause
on a time scale of 5 minutes. IMAGE will be launched on February
15, 2000 and placed in a polar orbit with apogee of about 7 Earth radii
(RE) where it will be well situated to observe the structure and dynamics
of the magnetospheric boundaries during geomagnetic storms. This talk will
review some of the key aspects of geomagnetic storms resulting from solar
eruptive events and how the IMAGE data may provide a revolutionary look
at this phenomenon.
