"Solar max," as scientists call it, is an 11-year cycle where the sun's magnetic field reverses polarity, typically spawning sunspots, flares, auroras and geomagnetic storms that, if large enough, can disrupt satellites and fry power grids on Earth. Over a period of about two years, "the...
23. As part of its 11-year cycle, the sun is now ramping up, after an unusually long lull. (Image credit: Solar Dynamics Observatory/NASAGoddard Spaceflight Center & the AIA Consortium) This article was updated at 10:42 a.m. EST on Feb. 2. A recent, prolonged lull in the sun'...
An ≈ 11.0-year tidal period with a direct physical relevance on the 11-year-like solar-activity cycle is highly improbable.doi:10.1007/s11207-023-02167-wCionco, Rodolfo G.Kudryavtsev, Sergey M.Soon, Willie W.-H.Springer NetherlandsSolar Physics...
An 11-year sunspot cycle is half of a 22-year Babcock–Leighton dynamo cycle, which corresponds to an oscillatory exchange of energy between toroidal and poloidal solar magnetic fields. At solar-cycle maximum, the external poloidal dipolar magnetic field is near its dynamo-cycle minimum strength...

Magnetic solar activity, the total radiative output from the Sun, and the Earth's mean global surface temperature all vary with the 11-year sunspot cycle in which the total number of sunspots varies from a maximum to a minimum and back to a maximum again in about 11 years. The terrestrial...
aIn addition to this 11-year cycle, there are many longer ones including an 80-to 100-year cycle that will heat to a peak around the year 2010. This could bring an even brighter sun. 除这个11年周期之外,有许多更长部分包括80对将加热对峰顶在年附近2010年的100年周期。 这能带来更加明亮的...
From this vantage point Solar Orbiter can capture the first ever images of the Sun's north and south poles from high latitudes, and never-before-observed magnetic environment there, which helps drive the Sun's 11-year solar cycle and its periodic outpouring of solar storms. ...
A composite record of the Sun's total irradiance compiled from measurements made by five independent space-based radiometers since 1978 exhibits a prominent 11-year cycle with similar levels during 1986 and 1996, the two most recent minimum epochs of solar activity. This finding contradicts recent...
The 11-year solar cycle, starting in the latter half of 2020 and coming to a close in about 2031, is expected to see its peak in 2024 to 2025, with frequent solar eruptions that may cripple the global communication and positioning as happened at its last peak on Halloween of 2003. "Kua...
