Short summary
The Earth’s radiation belt (ERB) is formed by energetic particles caught in the geomagnetic trap. Within the last two solar cycles (from 2001 to 2018), observations of the ERB by a fleet of low-altitude POES satellites have allowed for the discovery of an abnormal equatorward displacement of the outer part of ERB in the Siberian sector. This displacement can partially explain the increase in the occurrence rate of midlatitude aurora borealis observed in the Eastern Hemisphere.
