Short circuits in magnetosphere cause radiation spots on Earth

Recent data from clusters of ESA satellites show that solar radiation interacts with Earth's core, causing electromagnetic microstorms. By combining data from satellites orbiting at different distances from Earth, scientists discovered that bursty bulk flows, which are fast-moving ion bursts, are linked to intense magnetic field fluctuations near Earth's surface. These fluctuations are connected to field aligned currents high above Earth, confirming the relationship between bursty bulk flows and magnetic perturbations.
