This sunspot is not real. It is, however, one of the best models of a sunspot ever made. Scientists at the National Center for Atmospheric Research
produced this simulation by plugging the newest sunspot data into a 76-teraflop supercomputer. The image required nearly 2 billion data points to simulate the magnetism, temperature, and other features of a sunspot; it models the phenomenon down to a depth of nearly 4,000 miles.
