Solar activity on the Sun. - stock photo

November 1-2, 2011 - One large and two good-sized, energetic active regions are rotating into view. The magnetic connection between the upper two areas clearly begin to reach over and interact with each other. Above them, the magnetic field lines, made visible in extreme ultraviolet light by particles spiraling along them, rise out and loop back to the Sun, constantly changing their structures. As these regions rotate towards the center of the Sun, any solar storms they generate could produce effects here on Earth.
