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).

List of solar cycles. Solar cycles are nearly periodic 11-year changes in the Sun 's activity that are based on the number of sunspots present on the Sun's surface. The first solar cycle conventionally is said to have started in 1755. The source data are the revised International Sunspot Numbers (ISN v2.0), as available at SILSO. [1]
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 .
Solar cycle 18. Solar cycle 18 was the eighteenth solar cycle since 1755, when extensive recording of solar sunspot activity began. [1] [2] The solar cycle lasted 10.2 years, beginning in February 1944 and ending in April 1954. The maximum smoothed sunspot number observed during the solar cycle was 218.7 (May 1947), and the starting minimum was ...
