The Sun's magnetic field in high def

May 17, 2012
This HMI movie shows a sunspot region and the surrounding magnetic field. White = magnetic field pointing out of the Sun, black regions = into the Sun. Notice the tiny flux elements that cover the rest of the Sun; an example of HMI's extraordinary capabilities. These magnetic fields form the basis for the coronal loops and prominences you see in the AIA images.
