A good-sized active region with bright, towering arches began to rotate into view on April 19, 2018. The arches consist of charged particles spiraling along magnetic field lines revealed in this wavelength of extreme ultraviolet light. They rise up above the sun's surface many times the size of Earth. We will keep our eyes on this region to see if it has the kind of dynamism to produce solar storms.
