The sun emitted a large flare on July 12, 2012, but earlier in the week it gave a demonstration of how gorgeous solar activity can be. This movie shows the sun from late July 8 to early July 10 shortly before it unleashed an X-class flare beginning at 12:11 PM EDT on July 12 as captured by the Solar Dynamics Observatory (SDO).
