At the start of a solar cycle, active regions tend to appear around 30° to 45° latitude on the Sun's surface. As the cycle progresses, they appear at lower and lower latitudes, until they average 15° at solar maximum. The average latitude then continues to drift lower, down to about 7° and then while the old sunspot cycle fades, active regions of the new cycle start appearing at high latitudes.[3]

In solar physics Sporer s law is an empirical law for the variation of heliographic latitudes at which solar active regions form during a solar cycle 1 It was discovered by the English astronomer Richard Christopher Carrington around 1861 2 Carrington s work was refined by the German astronomer Gustav Sporer At the start of a solar cycle active regions tend to appear around 30 to 45 latitude on the Sun s surface As the cycle progresses they appear at lower and lower latitudes until they average 15 at solar maximum The average latitude then continues to drift lower down to about 7 and then while the old sunspot cycle fades active regions of the new cycle start appearing at high latitudes 3 See also editSolar variation Wolf number Joy s law astronomy References edit Hopkins Jeanne 1980 Glossary of astronomy and astrophysics Chicago University of Chicago Press ISBN 0 226 35171 8 Carrington Richard Christopher 1863 Observations of the Spots on the Sun from November 9 1853 to March 24 1861 Made at Redhill London Williams and Norgate Phillips Kenneth J H 1992 Guide to the Sun Cambridge Cambridge University Press ISBN 0 521 39788 X nbsp This article related to the Sun is a stub You can help Wikipedia by expanding it vte Retrieved from https en wikipedia org w index php title Sporer 27s law amp oldid 1217811125, wikipedia, wiki, book, books, library,
