Before a sunspot darkens the Sun’s visible surface, the magnetic activity that creates it is already developing out of sight. Those early changes are faint, but researchers say artificial intelligence can now recognize them hours before a new solar active region becomes visible.
A model called EarlyDetect detected signs of emerging active regions an average of nearly nine hours ahead of their appearance. The system was developed by a New Jersey Institute of Technology (NJIT) led research team and described Aug. 14 in the Journal of Geophysical Research: Machine Learning and Computation.
