'NASA’s chilling find': Flickering loops could predict sun’s explosive tantrums
Produced by: Mohsin Shaikh
Flickering Clues
Bright, erratic flashes in coronal loops were observed before powerful solar flares erupted.
Predictive Signs
NASA’s Solar Dynamics Observatory identified this flickering as a potential flare warning signal.
Loop Behavior
Coronal loops above active regions flickered much more than those in quieter sunspots.
Timing Advantage
Flickers peaked 2–6 hours before flares, giving researchers a valuable prediction window.
Accuracy Boost
Emily Mason's team estimates their method achieves 60–80% accuracy for flare predictions.
Snowflake Flares
“Every solar flare is unique,” said Kara Kniezewski, emphasizing the sun's dynamic corona.

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