The Sunspot Solar Observatory (SSO) is an astronomical observatory designed for the study of the Sun. The observatory is operated by New Mexico State University (NMSU) and the U.S. National Solar Observatory (NSO). It is split between operations at the telescope facility at Sunspot, New Mexico, and data and management at the Department of ...
Sunspot number is correlated with the intensity of solar radiation over the period since 1979, when satellite measurements became available. The variation caused by the sunspot cycle to solar output is on the order of 0.1% of the solar constant (a peak-to-trough range of 1.3 W·m −2 compared with 1366 W·m −2 for the average solar constant).
Sunspot, New Mexico. / 32.791; -105.818.

Solar cycle 11 (1867-1878) Drawing of the Great Sunspot of 1865. Solar cycle 10 was the tenth solar cycle since 1755, when extensive recording of solar sunspot activity began. [1] [2] The solar cycle lasted 11.3 years, beginning in December 1855 and ending in March 1867. The maximum smoothed sunspot number observed during the solar cycle was ...

Solar cycle 5. The Dalton minimum in the 400-year history of sunspot numbers, showing the low peaks for solar cycles 5 and 6. Solar cycle 5 was the fifth solar cycle since 1755, when extensive recording of solar sunspot activity began. [1] [2] The solar cycle lasted 12.3 years, beginning in April 1798 and ending in August 1810 (thus falling ...
Spörer's law. In solar physics, Spörer'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 Spörer .
