The Modern Maximum was found by Sami Solanki, Ilya G. Usoskin and colleagues [1] as the period of unusually high solar activity [2] which began with solar cycle 15 in 1914. It reached a maximum in solar cycle 19 during the late 1950s and may have ended with the peak of solar cycle 23 in 2000, as solar cycle 24 is recording, at best, very muted ...
Solar cycles still occur during these grand solar maximum periods, but the intensity of those cycles is greater. Likewise, extended periods in which the solar maximum is lower than average are labeled "grand solar minima". Some researchers suggest that grand solar maxima have shown some correlation with global and regional climate changes ...
An example is the Meeus smoothing formula, [7] with related solar cycles characteristics available in this STCE news item. [ 8 ] The start of solar cycle 25 was declared by SIDC on September 15, 2020 as being in December 2019. [ 9 ]
The Sun has reached a period of peak activity in an 11-year cycle known as the Solar Maximum, marked by recent geomagnetic storms and near-global aurora light displays.
NASA says the sun is in the highly active "maximum phase" of its 11-year solar cycle.. That means there will probably be big solar storms bringing beautiful aurora in the next year or so. Solar ...
Scientists said the sun is now in its solar maximum, or the peak of its 11-year solar cycle.
The solar luminosity is an estimated 0.07 percent brighter during the mid-cycle solar maximum than the terminal solar minimum. Photospheric magnetism appears to be the primary cause (96%) of 1996–2013 TSI variation. [70] The ratio of ultraviolet to visible light varies. [71]
