One way to track the solar cycle is by counting the number of sunspots, which are dark, cooler patches on the Sun’s surface.

The agencies that track sunspot activity say we’re now in peak solar activity, which has a big impact on the amount and southward extent of the Northern Lights. On Oct. 15, 2024 NOAA, NASA and the ...

Like the number of sunspots, the occurrence of solar flares follows the approximately 11-year solar cycle. But as the current Solar Cycle 25 approaches its peak, how are the number of solar flares ...

Solar scientists have spotted indications that the next solar cycle is beginning. That is despite the fact that it isn't due for another six years, and the current solar cycle (Cycle 25) is still in ...
