 Van_Allen_radiation_belt
Laboratory simulation of the Van Allen belts' influence on the Solar Wind; these auroral-like Birkeland currents were created by the scientist Kristian Birkeland in his terrella, a magnetised anode globe in an evacutated chamber.
In 1962, the Van Allen belts were temporarily amplified by a high-altitude nuclear explosion (the Starfish Prime test) and several satellites ceased operation.

 Van Allen radiation belts
Van Allen radiation belts, two belts (sometimes considered as a single belt of varying intensity) of radiation outside the earth's atmosphere, extending from c.400 to c.40,000 mi (c.650–c.65,000 km) above the earth.
The belts were named for James A. Van Allen, the American astrophysicist who first predicted the belts and then was first to interpret the findings of the Explorer satellite.
The charged particles of which the belts are composed circulate along the earth's magnetic lines of force extending from the area above the equator to the N Pole, to the S Pole, and circles back to the equator.

 Low Earth orbit - Wikipedia, the free encyclopedia
LEO is an orbit around Earth between the atmosphere and below the Van Allen radiation belts.
Orbits higher than this are subject to early electronic failure because of intense radiation and charge accumulation.
Orbits with a high inclination angle are usually called polar orbits, the properties of this and the Sun-synchronous orbit being more significant than their altitude.

 ScienceDaily: University Of Iowa's Louis Frank Uses Mathematical Data Analysis To Show Small Comets Are Real
Frank says that the mathematical formula applied to the data screened out possible causes of electronic noise such as longer wavelength radiation, energetic electrons and uneven sensitivity -- or "hot spots" -- among camera instrument pixels.
