THEMIS and the March 2007 Substorm

Visualizations by Tom Bridgman Released on December 10, 2007

NASA's Time History of Events and Macroscale Interactions during Substorms (THEMIS) mission observed the dynamics of a rapidly developing substorm in March of 2007. This visualization combines the orbits of the THEMIS satellites with a magnetohydrodynamical simulation of the Earth's magnetosphere corresponding to this time.

Opening with a view over the North geographic pole, we see the five THEMIS satellites moving along their common orbit. The camera then moves down into the equatorial plane and behind the Earth before we fade in the isosurface enclosing the regions where particles have at least 5keV of energy.

The camera moves down near the equatorial plane presenting a side view of the satellites in their orbits.

Red isosurfaces fade in, representing the boundary of regions where electron temperature (AKA mean energy) exceeds 5 kilo-electron volts.
