What to know about Physicists trace solar outbursts that led to historic Mother's Day storms

Physicists from the University of Iowa and other institutions have published a study in The Astrophysical Journal detailing how ten successive coronal mass ejections merged to create a historic geomagnetic storm in May 2024. The research utilized data from the 'Wind' instrument and computational modeling to explain the unusual intensity of the resulting auroras.

What happened

Physicists trace solar outbursts that led to historic Mother's Day storms Sadie Harley Scientific Editor Robert Egan Senior Editor On Mother's Day weekend in May 2024, Earth experienced its most powerful geomagnetic storm in two decades, spawning auroras—the…

Why it matters

In a new study, space physicists led by the University of Iowa report the most detailed account to date of a string of eruptions on the sun that produced the Mother's Day storms on Earth.

Common ground

The study, "Comprehensive MHD modelling of ten successive CMEs driving a historic geomagnetic storm—the 2024 Mother's Day event," was published in The Astrophysical Journal.

Perspective signals
