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. Over the period of a solar cycle, levels of solar radiation and ejection of … See more Solar cycles have an average duration of about 11 years. Solar maximum and solar minimum refer to periods of maximum and minimum sunspot counts. Cycles span from one minimum to the next. See more Sunspot numbers over the past 11,400 years have been reconstructed using carbon-14 isotope ratios. The level of solar activity beginning in the 1940s is exceptional – the last period of similar magnitude occurred around 9,000 years ago (during the warm See more Along with the approximately 11-year sunspot cycle, a number of additional patterns and cycles have been hypothesized. See more The 11-year solar cycle is thought to be one-half of a 22-year Babcock–Leighton solar dynamo cycle, which corresponds to an oscillatory exchange of energy between toroidal and poloidal solar … See more The idea of a cyclical solar cycle was first hypothesized by Christian Horrebow based on his regular observations of sunspot made between 1761 … See more Because the solar cycle reflects magnetic activity, various magnetically driven solar phenomena follow the solar cycle, including sunspots, … See more Solar Surface magnetism Sunspots eventually decay, releasing magnetic flux in the photosphere. This flux is dispersed and churned by turbulent convection and solar large-scale flows. These transport … See more WebApr 11, 2024 · In 1842, Heinrich Schwabe of Dessau, Germany discovered a distinct cycle — an 11-year period of increasing and decreasing sunspot activity. Since then, everything imaginable has been examined for a relationship to the 11-year sunspot cycle: the stock market, wars, epidemics, the price of whiskey, and even the fertility of fur-bearing animals …

WebSep 29, 2016 · More recently, other expressions of this solar activity have been highlighted, including solar flares, extremely short phenomena (a few hours at most) of radiation ejection and high-energy particles, which are responsible for the northern lights (read Solar energies). 1.1.
