  1. Jul 29, 2021 · How about solar magnetic storms, which are due to reach a cyclical peak in 2025—and could cause widespread havoc and trillions of dollars of damage on Earth. These storms reach a violent peak every 11 years, when the sun’s magnetic poles reverse and billions of tons of magnetically charged matter are expelled into the solar system.

    The dipolar component of the solar magnetic field reverses polarity around the time of solar maximum and reaches peak strength at the solar minimum.

  3. Sep 1, 2024 · The Sun's magnetic field goes through a cycle, called the solar cycle. Every 11 years or so, the Sun's magnetic field completely flips. This means that the Sun's north and south poles switch places. Then it takes about another 11 years for the Sun’s north and south poles to flip back again.

  4. Sep 15, 2020 · The Solar Cycle 25 Prediction Panel, an international group of experts co-sponsored by NASA and NOAA, announced that solar minimum occurred in December 2019, marking the start of a new solar cycle. Because our Sun is so variable, it can take months after the fact to declare this event.

  5. Jan 31, 2024 · The sun is getting ready to flip. Every 11 or so years, the sun undergoes an epic transformation: its magnetic poles reverse. Like on Earth, the sun has a magnetic North and a magnetic South....

  6. Dec 31, 2023 · As we approach the peak of Solar Cycle 25, we should expect to see more sunspots, each of which is a region of intense magnetic activity capable of producing solar flares and coronal mass ejections, or CMEs. This period of elevated activity can last up to several years, with impactful space weather events possible in 2024.
