This prediction is in line with the current general agreement in the scientific literature, which holds that solar cycle 25 will be weaker than average (i.e. weaker than during the exceptionally strong Modern Maximum). [7] However, observations from 2020 to 2022, the first three years of the cycle, significantly exceed predicted values. [12]
‘Significant change’ in Sun’s activity may come as good news for sky watchers ahead of next year’s solar eclipse
The sun emits the largest solar flare of this 11-year cycle, as imaged by NASA's Solar Dynamics Observatory on October 3. NASA/SDO NASA says the sun is in the highly active "maximum phase" of its ...
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] This makes cycle 24 the only "11-year solar cycle" to have lasted precisely 11 years.
2,300 year Hallstatt solar variation cycles. Periodicity of solar activity with periods longer than the solar cycle of about 11 (22) years has been proposed, including: The Hallstatt cycle (named after a cool and wet period in Europe when glaciers advanced) is hypothesized to extend for approximately 2,400 years.

Scientists said the sun is now in its solar maximum, or the peak of its 11-year solar cycle.
Solar maximum is the regular period of greatest solar activity during the Sun's 11-year solar cycle. During solar maximum, large numbers of sunspots appear, and the solar irradiance output grows by about 0.07%. [2] On average, the solar cycle takes about 11 years to go from one solar maximum to the next, with duration observed varying from 9 to ...
It's the biggest flare of this 11-year solar cycle, which is approaching its peak, according to NOAA. Sun shoots out biggest solar flare in nearly a decade, but Earth should be safe this time Skip ...
