Sun Earth Connection

The Sun emits electromagnetic radiation as well as particles in the form of the Solar Wind. The Solar Wind is highly variable over time. Large surges of particles can disrupt satellite orbiting the Earth and thus the predication of the solar “weather” is an area of great practical significance. Even though the Sun has been observed for many decades, there are still unanswered questions about parts of the solar electromagnetic spectrum. For example, the long-term behaviour of the UV radiation is still not well known, because it can only be measured from Space, where satellites have a limited life time.
