MagNet: Model the Geomagnetic Field - NASA
WEBDec 15, 2020 · Article. The efficient transfer of energy from solar wind into the Earth’s magnetic field causes geomagnetic storms. The resulting variations in the magnetic field increase errors in magnetic navigation. The disturbance-storm-time index, or DST, is a measure of the severity of the geomagnetic storm.
NASA Researchers Track Slowly Splitting ‘Dent’ in Earth’s Magnetic Field
WEBAug 17, 2020 · Earth’s magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun. But over South America and the southern Atlantic Ocean, an unusually weak spot in the field – called the South Atlantic Anomaly, or SAA – allows these particles to dip closer to the surface than normal.
