Coronal Mass Ejection and Earth’s Magnetosphere
A recent study shows that even subtle solar Coronal Mass Ejections (CMEs) can trigger intense geomagnetic storms, indicating that smaller CMEs are capable of causing major disturbances in Earth’s magnetosphere.
Coronal Mass Ejection (CME) and Geomagnetic Storms:
| Dimension | Key Details |
|---|---|
| Definition | Coronal Mass Ejection (CME) provides for a large expulsion of plasma and magnetic fields from the Sun’s corona. |
| Movement and interaction | CMEs travel through space at very high speeds and can disturb Earth’s magnetosphere, causing geomagnetic storms. |
| Associated solar phenomena | They are often associated with solar flares and active sunspot regions. |
| Impacts of geomagnetic storms | Geomagnetic storms comprise disruptions in satellites, power grids, navigation systems and radio communications. |
