This early sequence of images from the HMI imager is processed to reveal the magnetic field structure (magnetogram). White locations represent a positive magnetic field value (north polarity) while black represents a negative magnetic field value (south polarity). Gray is zero magnetic field.

Notice that the surface magnetic fields reveal much more structure than the white-light images in

SDO/HMI Continuum Full Disk View - April 7, 2010.

This full-disk view of the surface magnetic fields reveals far more details and structure.
