Coronal Mass Ejections (CMEs)
Coronal Mass Ejections (CMEs) are massive expulsions of plasma and magnetic field from the Sun's corona into space. These powerful eruptions are significant drivers of space weather phenomena and can have a range of effects on Earth and other planets in the solar system. CMEs typically occur in association with solar flares and are often triggered by the destabilization of the Sun's magnetic field. When a CME reaches Earth, it can cause geomagnetic storms, disrupt satellite operations, induce auroras, and even impact power grids and communication systems. The severity of the effects depends on factors such as the speed, size, and magnetic orientation of the CME. Space agencies and observatories monitor CME activity closely to forecast space weather and mitigate potential impacts on technological infrastructure and human activities. Understanding CMEs and their interactions with the Earth's magnetosphere is essential for space weather forecasting and protecting critical infrastructure. s://en.wikipedia.org/wiki/Coronal_mass_ejection
