This movie shows the Sun from the two STEREO spacecraft using the 171 Angstrom filter in the Extreme UltraViolet Imager (EUVI).
The 171 filter reveals ionized iron (Fe+8=Fe IX, Fe+9=Fe X), which forms at temperatures above 1,300,000K, and flows along the magnetic field lines of the solar active regions

This movie shows the Sun from the two STEREO spacecraft using the 304 Angstrom filter in the Extreme Ultraviolet Imager (EUVI).
This filter reveals ionized helium (He+1=He II), which forms at temperatures above 80,000K. This filter shows prominences and filaments above the solar surface
