Close-up of eruption event

This is a close-up view of the active region observed by Proba-2's SWAP instrument on 3 April 2010. Magnetic loops are visibly glowing - filled with cooling plasma (though cooling is a relative phrase - its temperature still exceeds a million degrees) - as the Sun's magnetic field knits itself together again in the flare's immediate aftermath. The area around them is still darkened due to the 'EIT wave' caused by the Sun's surface reacting to the force of the flare.
