Scientists Tracked a Monster Solar Region for 94 Days. Here’s What They Discovered
By combining observations from two space missions, scientists were able to follow one exceptionally active region on the Sun for months, revealing how its magnetic structure evolved over time. Our sun spins on its axis about once every 28 days. Because of that, any active region can be watched from earth for only around two [...]
In May 2024, the most powerful solar storm of the past 20 years broke out. And an international team of researchers from the Zurich Institute of Technology (ETH Zurich) was able to observe it, Phys.org reports. The sun rotates on its axis in 28 days. Therefore, active regions on the star can only be observed from Earth for up to two weeks in a row. After that, they go out of sight, remaining hidden for another two weeks.
Using the Solar Orbiter spacecraft, researchers were able to observe the active region of the Sun, which caused a huge geomagnetic storm in 2024, for 94 days, from its birth to its demise.
This Solar Region Didn’t Stop Erupting for 94 Days: What It Means for Earth
In a study published in Astronomy & Astrophysics, an international team of scientists led by ETH Zurich has unveiled the longest continuous observation of a solar active region ever recorded. Tracked for 94 consecutive days across the near and far sides of the Sun, this region, known as NOAA 13664, unleashed the strongest solar storm in over two decades, offering a critical leap forward in the understanding of space weather and its Earthly conse…
