The 15 pages that link to Sunspot, each with the reason it gives.

• Coronal mass ejectionRelated: Complex magnetic regions around sunspots can store energy that later powers eruptions.

• Solar cycleBroader topic: Sunspots are the most familiar visible markers used to track the cycle.

• Solar magnetic fieldBroader topic: Sunspots are the most familiar visible concentrations of the solar magnetic field.

• George Ellery HaleBroader topic: Hale investigated these regions and found that their magnetic polarities form patterns.

• Carrington EventRelated: Carrington observed the flare emerging from a large sunspot group.

• PhotosphereBroader topic: Sunspots are conspicuous photospheric features whose contrast comes from their lower temperature.

• Dialogue Concerning the Two Chief World SystemsRelated: Their observed motion supports a rotating Sun and challenges the idea of unchanging heavens.

• Solar physicsBroader topic: Sunspot patterns make the changing solar magnetic field visible.

• Solar stormRelated: Sunspots mark magnetically active regions where storm-producing eruptions often originate.

• Solar telescopeBroader topic: Solar telescopes track sunspot structure and evolution across the disk.

• Sunspot numberBroader topic: Individual spots provide the index’s second count.

• Annie S. D. MaunderBroader topic: These were the features Maunder tracked to reveal patterns in solar activity.

• Hale's lawBroader topic: Sunspots reveal the opposite magnetic polarities that define bipolar groups.

• Solar activity and climateBroader topic: Sunspot counts became a long-running proxy for changing solar magnetic activity.

• Solar phenomenaBroader topic: Sunspots mark magnetic concentrations where active regions develop.
