The Dunn Solar Telescope, also known as the Richard B. Dunn Solar Telescope, [ 1] is a unique vertical-axis solar telescope that specializes in high-resolution imaging and spectroscopy. It is located at Sacramento Peak in Sunspot, New Mexico. It is the main telescope at the Sunspot Solar Observatory, operated by New Mexico State University in ...
Alvena Storm. Alvena (Suhl) Storm (March 10, 1902 – June 11, 2003) [1] was the American Professor Emerita of Geography at San Diego State University (1926-1966) and a founding member of the department, serving as department chair. She was considered an expert in the geography of the Western United States.
Mount Laguna Observatory (MLO) is an astronomical observatory owned and operated by San Diego State University (SDSU). [1] The telescope was operated in partnership with the University of Illinois at Urbana-Champaign (UIUC) until 2000. MLO is located approximately 75 kilometers (47 mi) east of downtown San Diego, California, on the eastern edge ...

Solar cycle 25. 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. [3][4]
Chemical peels. An acid solution applied to sunspots causes the skin to eventually peel away so that new skin can grow. Chemical peels may cause a burning sensation that lasts a few minutes and ...
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).
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.
