View full credits

This movie shows the south pole of the Sun from the two STEREO spacecraft using the 171 angstrom filter in the Extreme UltraViolet Imager (EUVI). This filter reveals ionized iron (Fe+8=Fe IX, Fe+9=Fe X) which forms at temperatures above 1.3x106K, and flows along the magnetic field lines of the solar active regions. New active regions come into view as the Sun rotates.
