Solar storm DANGER! Intense solar flare explosion sparks blackouts on Earth, NASA says
On April 30, the forecasters from the National Oceanic and Atmospheric Administration (NOAA) warned about a sunspot, named AR3288, which was growing at an exponential rate and contained unstable delta-class magnetic fields. Just a day after the warning, the sunspot exploded, blasting a powerful solar flare in the direction of the Earth. As per NASA, it was an M7-class flare eruption and it sparked a radio blackout over the Atlantic Ocean region. The bigger question now is whether a solar storm is coming for the Earth.
