Sunspots and Magnetic Fields

The physical correlation of magnetic intensity and sunspots is clearly revealed when we fade back and forth between a filtered (i.e., white light) image of the Sun with a magnetic image (magnetogram) taken at the same time (Dec. 18, 2014). Two large sunspot groups with strong magnetic intensity stand out in both the magnetic and white light images.
