Massive sunspot that has DOUBLED in size in recent days could send solar storms careering toward Earth

Massive sunspot that has DOUBLED in size in recent days could send solar storms careering toward Earth: "A massive double-barrelled sunspot that has doubled in size in the past few days could now send a series of solar flares towards Earth. Though the severity of the disruption is yet unknown, some scientists are predicting the spot could send off medium-scale solar flares. These could cause radio blackouts and disruptions in the Earth’s polar regions."
