The night sky as far south as Florida glowed in hues of green, purple, and pink on Friday night as an extreme G5 geomagnetic storm blasted Earth’s magnetosphere. The gorgeous effect is the aurora borealis, or northern lights. The geomagnetic storm is caused by solar flares and coronal mass ejections (CMEs) from our sun. The CMEs are plasma bursts and magnetic field lines originating from our sun’s corona. The National Oceanic and Atmospheric Administration also observed a series of solar flares since last Wednesday. The solar flares have been associated with a sunspot cluster that is about 17 times the diameter of the Earth, and can cause disruptions to satellites, telecommunications, and power grids. An average 11-year cycle of the sun’s magnetic field typically sees four G5 geomagnetic storms.
