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 ...
1964 [7] San Diego State University ( SDSU) is a public research university in San Diego, California. Founded in 1897 as San Diego Normal School, it is the third-oldest university and southernmost in the 23-member California State University (CSU) system. The university offers bachelor's degrees, master's degrees, and doctoral degrees through ...
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 AR3664 has been growing over the past few days and is roughly 124,000 miles across-more than 15 times wider than the Earth. A sunspot this large is easy enough to see from Earth; all that ...

The solar cycle, also known as the solar magnetic activity cycle, sunspot cycle, or Schwabe cycle, is a nearly periodic 11-year change in the Sun 's activity measured in terms of variations in the number of observed sunspots on the Sun's surface.
Solar Dynamics Observatory. The detailed images recorded by SDO in 2011–2012 have helped scientists uncover new secrets about the Sun. The Solar Dynamics Observatory ( SDO) is a NASA mission which has been observing the Sun since 2010. [4] Launched on 11 February 2010, the observatory is part of the Living With a Star (LWS) program.
