Sun in extreme ultraviolet (EUV) at 171 Angstroms, taken by the two STEREO spacecraft using their Extreme UltraViolet Imager (EUVI). This filter reveals ionized iron (Fe+8=Fe IX, Fe+9=Fe X) which forms at temperatures above 1.3 million Kelvin, and flows along the magnetic field lines of the solar active regions. New regions of solar activity come into view as the Sun rotates left to right. | |
