Solar Storms Set to Illuminate the Skies: What You Need to Know.
A G4-class geomagnetic storm, the strongest seen in six years, hit the Earth on March 23, caused by huge amounts of solar winds entering the upper atmosphere of the Earth through a crack open in the planet's magnetic field. The storm can damage satellites, cause fluctuations in power grids, and disrupt GPS and shortwave radio. The event went undetected for several hours till disturbance in the upper atmosphere of the higher latitudes. The DSCOVR satellite by NOAA tracks different measurements of the Sun and its atmosphere to predict such events.
