IIA researchers develop 3D model to forecast arrival of Coronal Mass Ejections
Researchers from the Indian Institute of Astrophysics have developed a 3D simulation model to better predict the arrival and impact of Coronal Mass Ejections (CMEs). This model tracks magnetic flux ropes to understand how solar energy is released, potentially protecting satellite and power infrastructure.
Why it matters
Improved solar weather forecasting is critical for protecting global communication networks and power grids from space-based interference.
Researchers from the Indian Institute of Astrophysics (IIA), along with their collaborators from abroad, have developed a three-dimensional (3D) computer simulation model that can help more accurately forecast the arrival and impact of Coronal Mass Ejections (CMEs) before they reach Earth.
The CMEs are gigantic eruptions of magnetised plasma hurled from the sun at millions of kmph and when directed toward Earth, they can damage satellite systems, disrupt power grids, and interfere with global communications.
According to the Department of Science and Technology, at the heart of these eruptions lie magnetic flux ropes (MFRs), which are twisted bundles of magnetic field lines embedded in the plasma, and are widely regarded as the primary triggers of the CME.
