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 Earth¹s polar regions.
