The explosive peak in the sun 's roughly 11-year cycle of activity — known as the solar maximum — is already well underway, scientists have announced. While many experts suspected that this ...

We have tracked solar cycles for hundreds of years by counting the number of sunspots on the sun. Since December 2019, at the solar minimum marking the end of Solar Cycle 24, we have been in Solar ...

Scientists are keeping a close eye on the sun, and you might be surprised to learn that even if we've passed the peak of ...

The new 11-year cycle, called Solar Cycle 24, is expected to build gradually, with the number of sunspots and solar storms reaching a maximum by 2011 or 2012, though devastating storms can occur ...

The NOAA's Space Weather Predict Center said the current solar cycle is also stronger than the previous (Solar Cycle 24, 2008-2019), which explains in part why auroras have been much more widely ...

Solar activity is currently at a 23-year high, with Solar Cycle 25 more active than Solar Cycle 24, which occurred from 2009 through 2019. It's now approaching the strength of Solar Cycle 23 ...

Our sun has officially hit its solar maximum, with increased rates of auroras and solar flares expected in the coming months, NASA has announced. The sun goes through 11-year cycles of activity ...

Diagram showing the whole of Solar Cycles 23 and 24, and the first half of Cycle 25. For each cycle, the band of faster rotation starts well before the magnetic activity for that cycle.

“This is the big test for our models — whether Cycle 25 will play out about the same as Cycle 24,” Pesnell said. Another indicator of solar cycle progress comes from outside the solar system.

We are currently in Solar Cycle 25, which was forecast to be weak, like the preceding Solar Cycle 24. However, it appears that as we approach the next solar maximum, this solar cycle may be one of ...

September 2017 saw the declining phase of the previous solar cycle (Solar Cycle 24), which peaked in 2014.

From this graph, we can see that Solar Cycle 25 (from 2019 to present) has already exceeded the size of Solar Cycle 24. The largest individual sunspot month of the cycle so far, August 2024, had a ...
