Citizen Scientists Find That Persistent Sunspots Are Far More Dangerous

NASA citizen scientists have found that solar active regions lasting more than a month produce up to six times more intense solar flares than typical regions — with major implications for space weather forecasting.

Key Takeaways

Long-lived solar active regions are 3-6x more likely to produce X-class solar flares than typical regions
Citizen scientists classified Solar Dynamics Observatory image pairs to build the dataset behind this finding
