A SUNSPOT WITHIN A SUNSPOT? Sunspot 4172 looks like an ordinary sunspot group. However, data from NASA’s Solar Dynamics Observatory reveals something different–a possible sunspot within a sunspot.
This is a magnetic map of the sunspot group. The expected polarity of a sunspot in the sun’s northern hemisphere is . Indeed, Sunspot 4172 has that polarity. But it also has a knot of reversed polarity embedded within it. (Note the circled region in the animation, above.) Is this a strange mish-mash of opposite polarity sunspots? If so, it is unstable and likely to explode.
