Bright, erratic flashes in coronal loops were observed before powerful solar flares erupted.
NASA’s Solar Dynamics Observatory identified this flickering as a potential flare warning signal.
Coronal loops above active regions flickered much more than those in quieter sunspots.
Flickers peaked 2–6 hours before flares, giving researchers a valuable prediction window.
Emily Mason's team estimates their method achieves 60–80% accuracy for flare predictions.
“Every solar flare is unique,” said Kara Kniezewski, emphasizing the sun's dynamic corona.

Findings could safeguard astronauts, satellites, and power grids from harmful solar radiation.
Rather than trends, chaotic behavior in brightness offers a consistent prediction metric.
Automated systems might use brightness changes to issue timely space weather warnings.
