Van Allen belt Thesaurus Encyclopedia Wikipedia Van Al·len belt (văn ăl′ən) n. Either of two toroidal zones containing high-energy ionized particles trapped in Earth's magnetic field and surrounding the planet, beginning at an altitude of about 800 kilometers (500 miles) and extending...
Van Allen radiation belt, doughnut-shaped zones of highly energetic charged particles trapped at high altitudes in the magnetic field of Earth. The zones were named for James A. Van Allen, the American physicist who discovered them in 1958, using data tr
In the first of a series of experiments, an instrument package of eight Geiger counters, shielded and collimated in various ways, was carried aloft and released by an Atlas ICBM; its trajectory passed into the lower Van Allen radiation belt. Since there are variations in altitude at the iso...
•Van Allen belts/VABs: Not all of the solar particles are deflected by the magnetosphere, and some become trapped in the Earth's magnetic field. The particles are contained in one of two doughnut-shaped magnetic rings surrounding the Earth, the Van Allen radiation belts. The inner belt co...
Diagrams providing a cross-sectional view of the structure of the Earth's radiation belt and relationship to the plasmasphere. On the left is the usual structure of the two rings forming the Van Allen belt, while on the right the temporary third "storage ring" is seen, nestling between the...

2 Van Allen Probes Observations During the Storm 2.1 Overview of the 17 March 2013 Geomagnetic Storm The Van Allen Probes mission consists of two identically instrumented spacecraft (A and B) in nearly identical ~ 9 h orbits, with a perigee of ~ 600 km altitude, an apogee of...
We present cross-scale magnetospheric observations of the 17 March 2015 (St. Patrick's Day) storm, by Time History of Events and Macroscale Interactions during Substorms (THEMIS), Van Allen Probes (Radiation Belt Storm Probes), and Two Wide-angle Imaging Neutral-atom Spectrometers (TWINS), plus...
