Lying above the mesosphere, for 10 points, name this part of the thermosphere named after the charged particles it contains.
An Sq current system in this region can result in an equatorial electrojet. Solar flares cause disturbances in its lowest layer, resulting in shortwave fadeouts, and its E region or Kennelly-Heaviside layer reflects AM waves. Its F1 and F2 layers make up the Appleton layer, and geomagnetic storms in the magnetosphere result in auroras visible in this layer of the atmosphere. It is formed by solar radiation, which produces free electrons. Lying above the mesosphere, for 10 points, name this part of the thermosphere named after the charged particles it contains.
