What to know about Rare observations reveal an X9 solar flare before it erupts

A research team led by Louis Seyfritz analyzed data from multiple space telescopes to observe the lead-up to an X9-class solar flare. The study identified rhythmic plasma fluctuations and a gradual increase in brightness that preceded the eruption, potentially offering new insights for solar flare forecasting.

What happened

May 27, 2026 report Rare observations reveal an X9 solar flare before it erupts Sam Jarman Author Gaby Clark Scientific Editor Robert Egan Associate Editor Solar flares are powerful bursts of radiation from the sun's surface, which can wreak havoc on Earth's…

Why it matters

Yet despite decades of study, the processes that trigger these eruptions remain poorly understood.

Common ground

In a new preprint on arXiv, a team led by Louis Seyfritz at the New Jersey Institute of Technology has captured rare observations of a large flare in the hours before it erupted, offering new clues about what sets these events in motion.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
