The impacts of solar flares and CMEs can be significant, particularly for technological infrastructure. When these transients interact with Earth's magnetosphere, they can cause geomagnetic storms, disrupting satellite operations, GPS accuracy, and power grids. The study of Alfvénic fluctuations and solar wind turbulence is essential for predicting the severity of these events. Additionally, the effects of solar activity extend to the habitability of exoplanetary worlds, as the geometry of stellar Alfvén surfaces influences angular momentum loss rates. Understanding these processes is vital for mitigating risks associated with space weather and ensuring the resilience of critical systems.
