The Solar Cycle 25 Prediction Panel predicted in December 2019 [11] that solar cycle 25 will be similar to solar cycle 24, with the preceding solar cycle minimum in April 2020 (± 6 months), and the number of sunspots reaching a (smoothed) maximum of 115 in July 2025 (± 8 months). This prediction is in line with the current general agreement ...
As at Feb 20, 2025, solar cycle 25 is averaging 37% more spots per day than solar cycle 24 at the same point in the cycle (Feb 20, 2014). Year 1 of SC25 (Dec 2019 to Nov 2020) averaged 101% more spots per day than year 1 of SC24. Year 2 of SC25 (Dec 2020 to Nov 2021) averaged 7% more spots per day than year 2 of SC24.
The year 2024 was huge for solar news. In April, a total solar eclipse was visible to millions of Americans, which was then followed by multiple widespread northern and southern lights caused by CMEs.
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 ...
The peak of activity – the solar maximum – occurs when the sun's north and south magnetic poles flip. When that happens, the sun "transitions from being calm to an active and stormy state ...

A preliminary consensus by a solar cycle 25 Prediction Panel was made in early 2019. [24] The Panel, which was organized by NOAA's Space Weather Prediction Center (SWPC) and NASA, based on the published solar cycle 25 predictions, concluded that solar cycle 25 will be very similar to solar cycle 24. They anticipate that the solar cycle minimum ...
The sun produced its biggest flare in nearly a decade Tuesday, just days after severe solar storms pummeled Earth and created dazzling northern lights in unaccustomed places. “Not done yet ...
