Sun's coronal tail wags its photospheric dog

Solar physicists have long viewed the rotation of sunspots as a primary generator of solar flares -- the sudden, powerful blasts of electromagnetic radiation and charged particles that burst into space during explosions on the sun's surface. Their turning motion causes energy to build up that is released in the form of flares. But a team of scientists now claims that flares in turn have a powerful impact on sunspots, the visible concentrations of magnetic fields on the sun's surface, or photosphere. The researchers argue that flares cause sunspots to rotate at much faster speeds than are usually observed before they erupt.
