Summary

Description
English: Butterfly diagram showing paired pattern of sunspots. Graph shows sunspot numbers.
  • en:Spörer's law noted that at the start of an 11-year sunspot cycle, the spots appeared first at higher latitudes and later in progressively lower latitudes.
  • The en:Babcock Model explains the behavior described by Spörer's law, as well as other effects, as being due to magnetic fields which are twisted by the Sun's rotation.
