Aurinkosääilmiöt
Aurinkosääilmiöt refers to the conditions in space, particularly in Earth's magnetosphere, ionosphere, and atmosphere, that are influenced by solar activity. The Sun constantly emits a stream of charged particles known as the solar wind. Variations in this solar wind, along with solar flares and coronal mass ejections (CMEs), can have significant effects on Earth.
When the Sun releases a CME or a powerful solar flare, a large amount of plasma and
These particles can excite atmospheric gases, leading to the phenomenon known as aurora borealis (Northern Lights)
