The Sun is an active star that produces the most powerful explosions in the Solar System such as solar flares and solar storms. These explosions are often accompanied by fast particles with speeds comparable to the speed of light, sometimes directed towards Earth. The fast particles can have a harmful impact on satellites and technology in space. Some of these particles can be observed remotely as radio emission but they can also be directly detected by spacecraft. A number of mechanisms can produce these fast particles during solar storms. However, it is currently not known which type of storms and mechanisms produce the particles observed. The project aims to answer these unknown questions by using observations from international radio telescopes combined with direct detections of these particles from a newly launched fleet of spacecraft.
