Solar activity waxes and wanes on an 11-year cycle.The current cycle, known as Solar Cycle 25, began in December 2019 and is still in its maximum phase, experts say.

Scientists anticipate that the maximum phase will last another year or so before the sun enters the declining phase, which leads back to the solar minimum. Since 1989, the Solar Cycle Prediction ...

If this is true, then we could already be in the declining phase of Solar Cycle 25. This solar maximum date is very different from the original prediction of July 2025.

The recent flurry of solar storms suggests the sun is in a period of maximal activity as part of its 11-year cycle. The active period is likely to continue over the next year, so more auroras ...

But the sun had been primed to put on a show as it approached the maximum phase of its 11-year activity cycle—and that high activity continues today. This solar cycle still has the potential to ...

The solar cycle typically spans about 11 years, with the sun going from a quiet period of low magnetic activity to a highly active phase characterized by intense solar flares and solar storms.

Solar Orbiter is gathering data on phenomena including the sun's magnetic field, its activity cycle, and the solar wind, a relentless high-speed flow of charged particles emanating from the sun's ...

Solar activity waxes and wanes on an 11-year cycle. The current cycle, known as Solar Cycle 25, began in December 2019 and is still in its maximum phase, experts say.

Scientists anticipate that the maximum phase will last another year or so before the Sun enters the declining phase, which leads back to solar minimum. Since 1989, the Solar Cycle Prediction Panel ...
