The present solar cycle is unique in capabilities enabled by missions launched to the inner heliosphere (Solar Orbiter, Parker Solar Probe, BepiColombo) providing, for the first time, excellent possibilities for multi-spacecraft studies of SEP events combined with high-cadence, high-resolution solar observations of the eruptions from multiple points of view, including ground-based radio facilities. In addition, the new missions carry instrumentation that can provide in-situ measurements with much higher quality and resolution than so far possible. This has provided unprecedented opportunities to study collisionless shocks and energetic particles also with single-spacecraft heliospheric observations.
At the highest energies, instruments such as AMS-02 aboard the ISS and ground-based neutron monitors can provide information on GCR transport through the heliosphere. High fluxes of energetic particles of the highest energies can pose a severe radiation risk to crewed spaceflight and a significant threat to satellites. Particle precipitation also causes changes in the chemistry of the middle and upper layers of the Earth's atmosphere, thermodynamic effects in the upper troposphere and lower stratosphere region, and can influence components of the global electric circuit.
Several research projects of the EU Framework Programme have made use of these new capabilities and produced exciting scientific results and data analysis tools for the heliophysics community. We solicit contributions on energetic particles and heliospheric shocks, and their effects at Earth and other planets, that make use of the unique observational capabilities of the 25th solar cycle. A special emphasis will be placed on the recent results and prospects stemming from the European projects targeted on these topics, but other contributions are also welcomed.
