The region could send unexpected solar flares our way.
Scientists have detected a rapidly growing sunspot that’s pointed directly at Earth and could launch an assault of solar energy our way in the coming days.
A number of solar flares — large explosions of electromagnetic radiation that snap off from the sun's surface and launch outward into space— have been detected"crackling" around the spot, according to SpaceWeather. Fortunately, they are all currently C-class flares, which fit into the weakest of the three tiers of solar flares that government satellites track. A-, B- and C-class flares are generally too weak to have a noticeable impact on Earth.
Sunspots are large, dark regions of strong magnetic fields that form on the sun's surface. These regions — which typically measure as wide as planets — appear darker because they are cooler than their surroundings, according to Live Science's sister site Space.com. They form where bands of the sun's magnetic field become tangled and taut, inhibiting the flow of hot gas from the sun's interior and forming cooler, darker regions on the sun's surface.
