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).
Solar phenomena. v. t. e. Sunspots are temporary spots on the Sun's surface that are darker than the surrounding area. They are regions of reduced surface temperature caused by concentrations of magnetic flux that inhibit convection. Sunspots appear within active regions, usually in pairs of opposite magnetic polarity. [2]
Solar cycle 25 is the current solar cycle, the 25th since 1755, when extensive recording of solar sunspot activity began. It began in December 2019 with a minimum smoothed sunspot number of 1.8. [2] It is expected to continue until about 2030.
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 ...
SAN DIEGO, CA – San Diego State University Wednesday unveiled a $3 billion plan to expand the campus into Mission Valley and redevelop the SDCCU Stadium property over the next 15 years.
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.
The sunspot clusters are “magnetically complex and much larger than Earth,” the Space Weather Prediction Center said, noting continued growth in both the area of the sun experiencing flares ...
‘Magnetically Complex’ Sunspot Clusters. The watch comes after two massive sunspots merged, spitting at least two X-class (the largest class) and M-class (the second-largest class) solar ...
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]
Sunspots. CO 2, temperature, and sunspot activity since 1850. Early research attempted to find a correlation between weather and sunspot activity, mostly without notable success. [33] [34] Later research has concentrated more on correlating solar activity with global temperature.
