There was already a high probability that active region (AR) 2192 was going to erupt with a powerful solar flare, so it came as little surprise when two X-class flares erupted within 24 hours of eachother.
Eruptions on the sun's surface are probably caused by giant, unstable magnetic plasma arches, a new study reports — a discovery that brings scientists one step closer to predicting solar outbursts that can wreak havoc on Earth.
