👉 A coronal eruption is a type of solar phenomenon that occurs when a large amount of plasma, or gas, breaks off from the Sun and falls back into space. This process can be caused by a variety of factors such as solar flares, magnetic field disturbances, or changes in the Earth's orbit around the sun. Coronae are typically seen as bright white lines extending from the Sun's surface, and they can vary in color depending on their distance from the Sun.
