Important notice about STEREO Behind
Frenetic Active Region - May 16, 2007
In this 3D STEREO image of the Sun in extreme ultraviolet light (May 16, 2007) one can see two active regions with bright arcing loops above them. The bright region on the left particularly shows particles trapped along many tangled magnetic field lines. Active regions are areas of intense magnetic activity that appear brighter in extreme UV light, in this case the wavelength of 195 Angstroms. The 3D image was made by combining simultaneous images from the two STEREO spacecraft.
