3D Model for Predicting Coronal Mass Ejections

In August 2026, scientists developed a three-dimensional computer simulation model to improve forecasting of Coronal Mass Ejections (CMEs), including their speed, arrival time and potential impact on Earth.

Key Points

Coronal Mass Ejections: CMEs are massive eruptions of magnetised plasma from the Sun that can disrupt satellites, communications and power grids.
Magnetic Flux Ropes: The model traces twisted magnetic structures called magnetic flux ropes, which play a key role in triggering CMEs.
Magnetic Reconnection: The simulation showed that magnetic reconnection intensifies before the rapid expulsion of the flux rope into space.
CME Acceleration: Researchers found a clear relationship between the rate of magnetic reconnection and CME acceleration.
